Kihwal Lee updated HDFS-5449:
-----------------------------
Attachment: HDFS-5449.branch-2.patch
The branch-2 version of patch is attached. It is a straight port of the trunk
version. The difference is due to the use of the new get methods in trunk.
Locally tested. PreCommit won't succeed as the patch won't apply to trunk.
> WebHdfs compatibility broken between 2.2 and 1.x / 23.x

> Similarly to HDFS-5403, getFileBlockLocations() fail between old (1.x,
> 0.23.x) and new (2.x), but this is worse since both directions won't work.
> This is caused by the removal of "name" field from the serialized json format
> of DatanodeInfo.
> 2.x namenode should include "name" (ip:port) in the response and 2.x webhdfs
> client should use "name", if "ipAddr" and "xferPort" don't exist in the
> response.
