    Attachment: FsckBlockPlacement1.patch

Hairong, thanks for the comment. I updated the patch.
I missed the case that when replication is 2 we gurantee that the two recplicas will be on
two different racks.

> fsck currently detects missing and under-replicated blocks. It would be helpful if it
can also detect blocks that do not conform to the block placement policy. An administrator
can use this tool to verify that blocks are distributed across racks.
