Koji Noguchi commented on HDFS-729:
-----------------------------------
bq. Name node already has a list of all the corrupt/missing/underreplicated
blocks.
Fsck is useful when Namenode is misbehaving, like not replicating blocks, not
deleting over-replicated blocks, etc.
In those cases, Namenode's state is usually out of sync and not that useful.
> fsck option to list only corrupted files
