> While working on related issue, it was noticed there are some places in
> {{distcp}} that's better to be improved and cleaned up. Particularly, after a
> file is coped to target cluster, it will check the copied file is fine or
> not. When checking, better to check block size first, then the checksum,
> because the later is a little expensive.
