dhruba borthakur updated HADOOP-5027:
-------------------------------------

    Priority: Blocker  (was: Major)

I would like to add this to the Blocker list so that we can get a fix for this one in the
next release of 0.19.

> If a reported block has a different generation stamp then the one stored in the NameNode,
the reported block will be considered as invalid.  This is incorrect since blocks with larger
generation stamp are valid.
