Switching Careers: From Java to Big Data / Hadoop

Last updated on Jul 04,2019 25K Views

There is this point in all our lives where we think of switching careers or apprising our skill sets to improve our career growth or even just to stay updated with the growing trends. But careful analysis of the current trend and observing the requirements serves as a good method to choose which skill set get updated with. Looking at the current market, Hadoop and Big Data technology are growing extremely fast and has lots of market demands as well.  A surge in interest in “Big Data” is prompting many Development Team Managers to consider Hadoop technology as it’s increasingly becoming a significant component of Big Data applications. In doing so, taking inventory of the skills sets required when dealing with Hadoop is vital.  According to Helena Schwenk, analyst at MWD Advisors, quoted to SearchSOA.com that a well-rounded Hadoop implementation team’s skills should include experience in large-scale distributed systems and knowledge of languages such as Java, C++, Pig Latin and HiveQL. Data 

It is now clear that having knowledge on Java is an essential skill needed in Hadoop. Let’s go ahead and talk about how easy it is for you to switch from Java to Hadoop.

Why you need to Cross over from Java to Big Data?

  • A look in to Java and Hadoop job trends:

Job trend - Java to Big Data

While looking at the graphic representation of the job trends taken from Google, it is pretty obvious that the Hadoop job trend is so much better than Java. Saying this, it doesn’t mean that there is a downfall in Java based job trend. It is just that with the growing surge in Hadoop and the demand for the companies looking for Java experts with knowledge in Hadoop is too big to be ignored. This is clearly seen in the job trend graphic representation for ‘Java with Hadoop’ skill kind of jobs.

  • When checking for job requirements for Java with Hadoop skills, there is a huge demand, but not enough professionals with the above said skill to meet the requirements.  According to Developers Slashdot, JPMorgan Chase and other companies where looking for job applicants in this field at this year’s Hadoop World conference. It seems they couldn’t find enough IT professionals with certain skills that includes Hadoop MapReduce (MapReduce scripts written in Java). This means high pay.
  • According to Dice’s Open Web, Java is the leading skill hiring managers looking for Java-Hadoop combined skill. Hadoop with Java is a valuable skill as HDFS (Hadoop Distributed File System) is written in Java.
  • According to Business Insider, Hadoop is worth at least $103,000 per year as salary.
  • Job with Big Data skills pays more than $106,000 annually.

Why it’s easier for a Java professional to switch to Hadoop?

Hadoop is an open-source, Java-based programming framework that supports the processing of large data sets in a distributed computing environment. Based on Google’s MapReduce model, Hadoop distributes computing jobs and then combines results. The MapReduce scripts used here are written in Java. Now, it is pretty obvious that to work on Hadoop, knowledge in Java is imperative. And having knowledge in Java makes it a cake walk when it comes to switching over to Hadoop.

Now, the real question to be asked is about Hadoop’s staying power as a career path:

IBM, Microsoft and Oracle have all incorporated Hadoop this year. Other companies with Hadoop and looking for Hadoop professionals as on November, 2013 are:

  • Amazon (110)
  • eBay (53)
  • Yahoo! Inc. (37)
  • Hortonworks (36)
  • Facebook (33)
  • Apple (28)
  • General Dynamics – IT (28)
  • EMC Corporation (27)
  • Northrop Grumman (25)
  • Twitter (23)

This is a definite sign that Java to Big Data / Hadoop is the way to go.

    hi i am ashutosh i am btech in computer science but not very good in languages thats why i work in BD in e-commerce company but now i want to make my career as a big data scientist but one of my friend told me that you should be very good in maths and myself not very good in maths also ,so my Question is can i make it to big data

    • EdurekaSupport says:

      Hi Ashutosh, your understanding is right, you got the right inputs from your friend. Data scientist is a specialized role that cover concepts of Hadoop, Mahout and R. If you want to move in to Analytics domain, the entry point may be R, however a quantitative aptitude and affinity to deal with data is essential.

  • Vignesh says:

    Hi this is vignesh i have 3.5 years of experience in Java/j2ee and related technologies. I also took hadoop training from edureka and also i am edureka certified hadoop developer. So after gaining some practical knowledge and doing some POC on Mapreduce, Now i have planned to switch job into BigData industry.

    Now my concern is i have good knowledge on Hadoop 0.20 and 1 . I like to know which version of hadoop is effectively used in market as a standard now?

    Knowing Hadoop 0.20 and 1(Mapreduce Java , Basics of Hive , Basics of Pig and Hbase) is enough to grab Hadoop Developer job???

    I do not have any experience in Hadoop, So does edureka provided certificate helps me in showing my POC?? Does industries recognize this certificate??

    Please advise .
    Thanks,
    Vignesh

    • EdurekaSupport says:

      Absolutely Vignesh!! Edureka’s certification is a testimonial to the fact that you have hands-on experience in Hadoop. Hadoop 2.0 is the requirement of the industry for sure, along with Hadoop 1.0 and the is the new in thing. My suggestion is, while looking for a job you can stay connected with Edureka and work on another project, maybe on Pig or Hive. This will definitely add more value to your resume. Hope this helps!!

  • Leela Srinivas says:

    I am a Backup Admin (Symantec Netbackup, EMC Avamar and Data Domain & Storage Technologies) with 7+ years of experience. I would like to learn Hadoop Developer training program and move into development side only. I am much more interested into development side rather than admin side. I am a novice in Hadoop and it’s technology and programming side and my entire experience in admin side only. I do not know anything about Hadoop (ie: not even abcd of it). I do not know anything about programming ie: Java or SQL things, maybe I have forget after my engg. I have completed my B.Tech (Information Technology) in computers stream in 2006. Please kindly help and suggest me if this is the correct move/decision at this time and let me know if I will have the opportunities with this kind of decision/move. I would like to know if there are any people with these kind of success rate? and is it a good decision/option at this point? Future on, I never ever want to go to Admin field. Will the Cloudera Certified Developer for Apache Hadoop (CCDH)(Exam Code: CCD-410) or any other Hadoop Developer certification be added advantage? Please kindly help me and suggest me with the right career path in this regard as I am not at all interested in any kind of admin job/field/stream(sorry to say this). I have checked up few institutes/training centers but feel doubt, are they trying to earn money and somehow the individual join their institute? Also, is it possible to help modify my resume accordingly or show any references or provide any guidance to thru the interview or any case in this regard? Will they provide require/necessary Java and SQL programming training for the individual(ie: like me who aspire to go for development side only) to cope up for the Hadoop Developer Training/Certification to clear on and also for the interview as well? I am feeling fear at this point. But I would like to take the step and do real hard work and put all my complete efforts and give it a try. If fail, whats the path in this case!!!

    Feeling very much fear to change my career path. Please help!!!!

    Please kindly let me know if any institute/training center who can help me with the best training and provide guidance and career path rather than getting money out of the individual.

    I would sincerely appreciate any kind of suggestion/advice’s in this regard. Also, I would like to pursue the Hadoop Developer training program and the cost involved for the Hadoop developer training program ie: classroom training. and timings for the training as well. Any weekend batches for working professionals doing night shift(like me)?

    Apologise for any inconvenience/hurt caused in this regard. Looking for a support and true help in this regard.Thank you very much in advance.
