Hi Everyone,
I am starting my hadoop cluster manually from Java which works fine
until some time. When secondary NameNode tries to do merge it gives me
the following exception:
---------------------------
13/10/03 10:29:38 ERROR namenode.SecondaryNameNode: Throwable Exception
in doCheckpoint:

What causes this exception to occur?
Any help would be appreciated!
