With big data gaining traction in IT industry, companies are looking to hire competent hadoop skilled talent than ever before. The best way to understand about the different technical professionals working with HDFS, MapReduce and the entire Hadoop ecosystem is to have a look at various Hadoop job descriptions -which is a mixed bag ranging from developers to data scientists. Many students or professionals are concerned about acquiring expertise in different hadoop components and this list of job titles for hadoopers will help them make the right decision by assisting them in choosing the desired job role as a Hadoop expert.
If the question is, does the certification make a difference in getting job as a Hadoop developer, Hadoop Architect or a Hadoop admin - here is the answer. Yes, the industries are looking for skilled professionals. Hadoop jobs are highly lucrative and it comes with a price of knowing the technology in depth.
An industry in big data, if seen with a top down approach to understand the Hadoop jobs offered, we can tear it down and say, that at top we find Hadoop Architect’s job who designs how the system should work. Later, Hadoop Developer's job is to actually write programs and bring the visions of Hadoop Architect to reality. And then there is testing, considered last but an important job. A Hadoop Tester’s job is to take care of all the checks to make a piece of code stable as possible.
