Hairong Kuang updated HDFS-679:
-------------------------------

      Resolution: Fixed

The failed core test was caused by HDFS-690.

I've committed this.

> When I run TestClientProtocolForPipelineRecovery, I always see that the block receiver
throws IOException complaining about mismatched checksum when receiving the last data packet.
