> From the log, I guess this is what has happened in order:
> 1 Process A open a file F for write.
> 2 Somebody else called recoverLease against F.
> 3 A closed F.
> The root cause of the missing block is that recoverLease increased gen count
> of blocks on datanode whereas the gen count on Namenode is reset by close in
> step 3. I think we should check if the last block is under recovery when
> trying to close a file. If so we should just throw an exception to client
> quickly.
> Although the issue is found on a 2.4 HDFS, it looks like the issue also exist
> on the trunk from code. I'll post a patch soon.
