I was a frontend developer, and I am new to hadoop or anything related to big data.
I am currently working as a Hadoop developer and I get to work on one of existing codebase also I am trying to recollect Java which I learnt during college.

Can u please provide me any inputs on how to get started with Hadoop, a personal view point on scope and future of Hadoop. A rough time span of how long it took for you to get out of the noob zone.

If you could provide me with a good tutorial or blog that would be awesome.

Thanks in advance
