Suresh Srinivas resolved HDFS-2320.
-----------------------------------

      Resolution: Fixed
    Hadoop Flags: [Reviewed]

I committed this patch. This patch is only relevant to 0.20.205, due to merging 0.20-append changes and is not relevant to trunk which has a new implementation of append.

> 0.20-append changes have been merged to 0.20-security. The merge has changes to version numbers in several protocols. This jira makes the protocol changes compatible with older release, allowing clients running older version to talk to server running 205 version and clients running 205 version talk to older servers running 203, 204.
