Hadoop Developer In Real World review for 2024

In our review of this course, we try to help you answer all of your most important questions about Hadoop Developer In Real World as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use HDIRW as an abbreviation of the course name?

During our Hadoop Developer In Real World course review, you might sometimes see us refer to it as HDIRW for the following 2 reasons:

  1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
  2. We’re lazy and HDIRW is simpler and easier for reviewing purposes

The full course name is 30 characters long, including blanks, while HDIRW is 5 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 25 characters every time we use HDIRW.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to HDIRW throughout the remainder of this review.

Is the Hadoop Developer In Real World course for you?

To determine whether Hadoop In Real World’s Udemy course is a good fit for you or not, ask yourself the following questions down below.

The more you answer “yes” to each question, the more likely it is that you’ll like this course.

Can you understand what Hadoop In Real World’s course is about in 30 seconds or less?

Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that Hadoop In Real World chose for the course, “Hadoop Developer In Real World”, as well as its subtitle: “Free Cluster Access * HDFS * MapReduce * YARN * Pig * Hive * Flume * Sqoop * AWS * EMR * Optimization * Troubleshooting”.

This combo of title and subtitle should be enough to communicate the purpose of the training if Hadoop In Real World is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what HDIRW is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Among other things, it means Hadoop In Real World hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.

For similar reasons, it’s important that you’re able to clearly understand what Hadoop Developer In Real World is all about from the first few lines of the course description.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of Hadoop In Real World’s official description of HDIRW

From the creators of the successful Hadoop Starter Kit course hosted in Udemy, comes Hadoop In Real World course. This course is designed for anyone who aspire a career as a Hadoop developer. In this course we have covered all the concepts that every aspiring Hadoop developer must know to SURVIVE in REAL WORLD Hadoop environments.

The course covers all the must know topics like HDFS, MapReduce, YARN, Apache Pig and Hive etc. and we go deep in exploring the concepts. We just don’t stop with the easy concepts, we take it a step further and cover important and complex topics like file formats, custom Writables, input/output formats, troubleshooting, optimizations etc.

All concepts are backed by interesting hands-on projects like analyzing million song dataset to find less familiar artists with hot songs, ranking pages with page dumps from wikipedia, simulating mutual friends functionality in Facebook just to name a few.

(Read more about this course on the official course page.)

Does HDIRW pass the 30 Seconds Test?

You can read a lot more about Hadoop Developer In Real World on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?

If so, Hadoop In Real World has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.

And, if not, maybe you’re better off looking at other IT & Software classes that are more clearly defined and more tailored to your specific interests.

Did Hadoop Developer In Real World appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with HDIRW above, what is your gut reaction to this IT & Software course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?

Did Hadoop In Real World do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, Hadoop In Real World’s online course is certainly worth considering some more.

But if not, perhaps it’s in your best interest to consider some other IT & Software courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.

Does Hadoop In Real World sound like a course instructor you’d like to learn from?

You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the HDIRW course is worth taking.

We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, Hadoop In Real World’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.

There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.

(FYI, all Udemy instructors, including Hadoop In Real World, have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).

Opening lines from Hadoop In Real World’s Udemy bio

We are a group of Senior Hadoop Consultants who are passionate about Hadoop and Big Data technologies. We have experience across several key domains from finance and retail to social media and gaming. We have worked with Hadoop clusters ranging from 50 all the way to 800 nodes.

(Learn more about this instructor on the official course page.)

What did you think about Hadoop In Real World after reading just the first few lines of the bio above?

After reading just the first few lines about Hadoop In Real World, did it make you more or less interested in taking the HDIRW course?

And did it make you feel like Hadoop In Real World was more or less credible and qualified to teach Hadoop Developer In Real World?

Finally, overall, did you feel like you’d receive the proper training from the instructor of this IT & Software course?

As always, we encourage you to listen to your gut instinct, which is different for every student.

Are the HDIRW lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the Hadoop Developer In Real World course, is that the instructors are constantly updating them, including adding and renaming lessons.

So it makes no sense whatsoever for us to list out all the modules and lessons in the HDIRW course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.

We do, however, have some tips about reviewing Hadoop In Real World’s course structure, so that you can get a better sense of whether this program is worth your time or not.

In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, Hadoop Developer In Real World, as well as the course’s subtitle, Free Cluster Access * HDFS * MapReduce * YARN * Pig * Hive * Flume * Sqoop * AWS * EMR * Optimization * Troubleshooting.

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that HDIRW is potentially a good, useful course for you, and you can have more confidence in Hadoop In Real World’s teaching abilities and lesson planning.

On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.

Have you taken some free lessons from Hadoop In Real World that you enjoyed?

Have you already learned something from Hadoop In Real World that you valued or enjoyed?

For example, does the Hadoop Developer In Real World training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)

But if you weren’t able to get any HDIRW lessons for free, have you perhaps watched a YouTube video by Hadoop In Real World, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of Hadoop In Real World’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with Hadoop In Real World’s teaching methods, and the more you enjoy them, the more likely it is that Hadoop Developer In Real World will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from Hadoop In Real World before purchasing this course, since it’s one of the best ways to determine whether HDIRW will be helpful for you.)

Are “Hadoop Developer In Real World” reviews generally positive?

On the bottom of the HDIRW page, you can read student reviews of the class.

Prior to February 26, 2024, there were 3,569 students enrolled, 1,311 reviews / ratings, and it was overall rated 4.6 out of 5.

Obviously, the more highly other students rate HDIRW the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the HDIRW reviews to get an overall sense of them. You don’t have to read each one!

Is Hadoop In Real World responsive to student questions in the HDIRW training?

You can see what other students have to say about this in their HDIRW reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send Hadoop In Real World a message through this system quite easily, even if you haven’t bought HDIRW yet.

For example, you could say, “Hi, and I came across HDIRW while looking at IT & Software courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in Hadoop Developer In Real World on your own, online?

This is a big one, because Hadoop Developer In Real World is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Hadoop Developer In Real World.

Yes, you will be able to interact with the students and the teacher, Hadoop In Real World, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of HDIRW make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Hadoop Developer In Real World training that looks something like this:

  • The purpose of HDIRW can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
  • Hadoop In Real World is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
  • Other HDIRW students have great things to say about the program

Other benefits include:

  • You get to go through HDIRW at your own pace
  • You join a community of 3,569 other students taking the course
  • You get lifetime access to the training
  • All updates to the training are free
  • You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that HDIRW would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford HDIRW?

Can you comfortably afford the cost of Hadoop Developer In Real World?

This is an important question to answer, because even if you think HDIRW sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before February 26, 2024, the price was $199.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on HDIRW with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on Hadoop Developer In Real World?

By far, the easiest way to get the best and biggest discount on this course is to use the Hadoop Developer In Real World discount code link at the top of this page.

It will instantly give you the best coupon code we could find for Hadoop In Real World’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best HDIRW course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting HDIRW for a better price, but also with any other Hadoop In Real World Udemy course that you’d like to get for cheaper.

How can Google help you get a HDIRW discount?

To use this method, do a Google search for the HDIRW training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy Hadoop Developer In Real World promo code” or “Hadoop Developer In Real World udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with Hadoop In Real World’s name and see what happens.

For example, you might do a Google search for “Hadoop In Real World Udemy coupons” or “Hadoop In Real World course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “Hadoop Developer In Real World coupons” rather than “Hadoop In Real World coupons”.

How can a Udemy sale get you HDIRW for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get HDIRW for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if Hadoop In Real World decides not to participate in the site wide sale, then you won’t get a discount on HDIRW, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the HDIRW course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a HDIRW discount from Hadoop In Real World?

If you’re really serious about getting “Hadoop Developer In Real World” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from Hadoop In Real World, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get Hadoop In Real World’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in Hadoop Developer In Real World. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join Hadoop In Real World’s mailing list, if you can find it, and then you hope that at some time HDIRW will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get HDIRW for free?

Of course, the best possible price for the HDIRW training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that Hadoop In Real World has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “Hadoop Developer In Real World free coupon” or “Hadoop Developer In Real World 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even Hadoop In Real World has offered free coupons for HDIRW in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a HDIRW free download?

It’s important to understand that there’s a difference between getting full access to the HDIRW training for free legally with a free coupon code vs. finding a way to download HDIRW illegally.

If you really want to go the download route, you can do a google search for something like “Hadoop Developer In Real World download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “Hadoop Developer In Real World free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, Hadoop In Real World created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 3,569 students enrolled in the program.

Can you get a refund on Hadoop Developer In Real World if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the HDIRW training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into Hadoop In Real World’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on HDIRW no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the HDIRW training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing Hadoop In Real World could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing HDIRW and not liking it, since you can always get your money back.

What is OCP’s overall rating of Hadoop Developer In Real World?

During this HDIRW review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.

So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.

Anyway, after taking a look at the HDIRW training, the instructor, Hadoop In Real World, and reading what other students have said about this program, we give it an overall rating of 4.9 out of 5.

Ultimately, though, what matters most is what you would rate it based on the same criteria.
