    Hi Siva
    both secondarynamenode and checkpoint node are merging edits log with FSimage and uploading the same to
    the namenode, so how different these two nodes are. What is that extended feature check point node is
    providing over secondarynamenode. (I have gone through secondarynamenode and checkpointnode post but
    not convinced yet).
    Awaiting your reply.
    Thank you

I have attended Siva’s Spark and Scala training. He is good in presentation skills and explaining technical concepts easily to everyone in the group. He is having excellent real time experience and provided enough use cases to understand each concepts. Duration of the course and time management is awesome. Happy that I found a right person on time to learn Spark. Thanks Siva!!!
