The practical value of a Bachelors or Master’s degree is controversial for a Hadoop developer because few of the big data companies hiring for Hadoop developers insist on a degree just to cut down on their pile of resumes. Companies believe that university curriculums are too focused on theoretical aspects but being a Hadoop developer requires real world problem solving capabilities. For some of the specialized big data roles like that of a data scientist, companies prefer candidates who have completed PhD in a statistical or numerical discipline. So, if you are from a Statistics, Physics or business analytics background – you can definitely create a meaningful benchmark as a Hadoop Developer in the workplace by mastering Hadoop skills with real time hands-on projects.
How do you work around the years of experience needed to become a Hadoop Developer?

What do recruiters look for when hiring Hadoop developers?
The battle is real when it comes to choosing between skills and experience. Someone who has enough experience and the right kind of Hadoop skill is the perfect person for the job.
Recruiting managers in the big data world have limited resources to base their judgement on. Hence there is a huge debate on what is the right amount of experience needed for a Big Data job. Some of the big data employers favour experienced, older and more mature people who have previously worked on one or two big data projects whilst some of the big data Hadoop jobs are targeted towards insanely dedicated people who can stay up all night coding big data applications. Thus, Hadoop career opportunities are meant for experienced professionals and also for young rock star IT professionals.
The job role of a Hadoop developer is playing with large datasets to program big data applications and anybody capable of doing it is the right fit for employers regardless of the experience. Preferably, an individual with an average of 0-3 years of experience in the IT industry can head on to pursue a lucrative career in Hadoop.

A common dilemma for to be Hadoopers is –“How much importance is given to a certification in Hadoop?” With technologies like Hadoop being new to be testable, employers look for certifications as an option to test the ability of the developer. Employers value certification just to determine if an individual really is well-versed with Hadoop concepts that he claims to know. There are several Hadoop certification programs provided by Cloudera, Hortonworks, MapR, and IBM that aim at testing your competence in Hadoop.
There are several Hadoop course providers like DeZyre who aim at teaching Hadoop by focussing on practical solutions and not theoretical conundrums. They also provide accredited hadoop certification on successful completion of the hadoop projects. Candidates can master Hadoop skills by working on hands-on projects which can be appealing to companies who are looking to scrutinize candidates on their ability to deliver real-world big data solutions. When the needs of the employer and certification are aligned with each other, it is a WIN-WIN for both the employer and the Hadoop developers.
