Kihwal Lee commented on HADOOP-8001:
------------------------------------
+1 The patch looks good.
The create() method already overwrites the existing checksum file, so doing
this in rename() should be okay.
> ChecksumFileSystem's rename doesn't correctly handle checksum files

> Rename will move the src file and its crc *if present* to the destination.
> If the src file has no crc, but the destination already exists with a crc,
> then src will be associated with the old file's crc. Subsequent access to
> the file will fail with checksum errors.
