But as we all know things change and currently there’s a new area in the technology world which is getting a lot of attention, big data. Big data has been said to be one of the most lucrative fields currently and big data Hadoop developers are in great demand.

Big data is used across different industries

Switching your career to big data will help you to work in different industries other than IT or software. Big data analytics is used across various industries like healthcare, consumer, technology, banking and energy. 

How can you make the move?

You must have often heard about software developers making a switch to big data. Here is how you can make it without a lot of efforts: 

Hadoop is Java-based

Since Hadoop is a Java-based programming framework used extensively in big data, switching to big data/Hadoop is easy for Java professionals. The processing engine of Hadoop, MapReduce, is basically written in Java programming language. Thus, in order to deploy Hadoop frameworks successfully, one must be fluent in the Java language. 

Big data industry needs Java developers

Organizations who are using Hadoop framework to perform big data analytics need Java developers. They wouldn’t want someone whom they have to train in Java. These companies pay a large salary hike to get the best Java developers who can work in Hadoop. 

Getting certified

Most of the high-paying jobs in the big data field are for experienced professionals. If you have practical knowledge in Hadoop or have a certification, the chances of getting a good hike are higher. There are various Hadoop certifications which you can enroll in to become an expert. 

Bottom Line

If you are worried about the IT jobs getting stagnant, you just need to rethink your career options and move on from being a Java software developer to a big data career. You will feel later that you have made the correct decision and keep up with the changing technology landscape.
