> In the situation where the block lost all its replicas, fsck shows the block
> is missing as well as corrupted. Perhaps it is better not to mark the block
> corrupted in this case. The reason it is marked as corrupted is
> numCorruptNodes == numNodes == 0 in the following code.
> {noformat}
> BlockManager
> final boolean isCorrupt = numCorruptNodes == numNodes;
> {noformat}
> Would like to clarify if it is the intent to mark missing block as corrupted
> or it is just a bug.
