Updated on 24th May, 23 10499 Views

Java was a popular programming few years back and every technical professional wanted to master this technology to build a career in IT industry. However with the emergence of Big Data, some of the advanced frameworks evolved which are highly in-demand across all the industries worldwide. One of them is Hadoop which is opening new and lucrative career opportunities for beginners as well as professionals in various domains.

The reason behind such hype about Big Data is:

  • The growing importance of dark and untapped data
  • The need for analytics and research for predicting the trends
  • The data emanating from numerous sources making it imperative to accommodate them using powerful technologies
  • Increasing need for real-time data processing

Top Reasons you should be Upgrading your Java Career to Hadoop!

Let us compare the two job profiles in terms of the salary hike, responsibility increase, and the vast opportunities.

Java is the programming language of choice for Hadoop

As you are aware Hadoop is a massive Open Source platform for working on extremely huge volumes of data that is beyond the capacity of traditional database management tools. It needs huge commodity hardware support and processing power of the distributed computers in order to successfully run it in any environment.

It is a framework that owes a big part of its success to the Java language. The processing engine of the Hadoop ecosystem is MapReduce framework which is basically written in Java programming language. So in order to successfully deploy MapReduce in a Big Data environment, knowledge of Java is essential. So if you are already a Java developer then it becomes quite easy for you to write the MapReduce scripts that shall be extensively deployed on the Hadoop cluster for Big Data computational jobs.

HDFS also has the Java programming language at its core. If you have a prior expertise in Java then you can easily write the files that are in the local file system onto the HDFS through the deployment of Java programming language.

Hadoop deployment is rising with each passing day

As you are aware Hadoop is being extensively used by both small and large companies in order to make sense of all the Big Data that is being created on a regular basis. You have to remember that 90% of all data that we have today was created in the last two years alone!

So a switch over to Hadoop will also give you a big boost in your career since now automatically you will be working in a domain that has huge upside and wider roles and responsibilities that you can assume depending on your key skill sets and interest.

It’s not just about Big Data Hadoop but about the whole ecosystem that is interconnected in multiple ways. This platform is used to organize and utilize the data that is available all across in abundant measure. For that you need the skills in ETL (Extract, Transform, Load), and also clear understanding of data warehousing and Java skills are much sought-after. You also need to extensively work with NoSQL database systems like HBase, MongoDB and Cassandra. Now Java powers all these various technologies and tools giving you a mighty head start in your career.
