Robert Joseph Evans commented on HADOOP-8001:
---------------------------------------------

The patch looks good to me too.  It is a bit confusing to have dst refer to the destination in some cases, and the checkfile in others.

> 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.
