Nicolas Spiegelberg commented on HDFS-617:
------------------------------------------
@Hairong: Dhruba asked that I not bump the version number so 0.20-append DNs
will be backwards compatible with 0.20.3. If you notice, I keep the old APIs
around. I also revert back to the old recursive create on the HBase side if
anything the new api usage fails.
@Todd: we could probably remove the deprecation warnings. Technically, the
deprecation rev is 0.21, because these apis are removed in 0.22.
