Hi Onkar , To answer your questions ( Precisely to get in to hadoop ) Ans1. Before joining any weekend batch, you can check "bigdatauniversity.com ". Register for free and get some good learning videos from it . Weekend batch only confirms minimal guideline for Hadoop like installation of hadoop single node cluster , understanding of HDFS , hadoop ecosystem, introduction to few tools in hadoop ecosystem. No practical or demo project covered in online class. Ans2. Learning Hadoop is not big deal but implementation of same is challenge in practical scenario. you can learn it in month or two. Ans3. In Hadoop Job Market, either sql or java background is preferred by employer.Its not easy to get job with only learning hadoop. You need to shown some experience in working either in Hadoop or in java/sql. My Advice : If you really interested Hadoop , try to install Hortonworks sandbox on oracle virtualbox and then practice it with some practice scenarios. Else you can check online hadoop single node installation and practice it . you can mail me in case of any queries related to Hadoop

If looking for Hadoop (And with the mindset you have :) ) , you go for Data Scientist role or Hadoop Analyst role. These roles need lot of analysis and you wont get bored . Apart from this , I would suggest to continue in the same field and try to focus on automation of your daily tasks or creation of GUI for your backend tasks etc. Dont think differently, think from client's point of view. Think as if you are client , you need this function/facility, how you would have design it for best possible usage. It will not only make you feel good but also give you new direction to personally growth in IT.
