    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
