Tsz Wo (Nicholas), SZE updated HDFS-2065:
-----------------------------------------
Hadoop Flags: (was: Reviewed)
I suggest we simply change null in DFSClient.getFileChecksum(..) in this issue
since it is a bugs in 0.20. We may think if FSNamesystem.getBlockLocation(..)
should be changed seperatedly.
