Kihwal Lee created HDFS-5449:
--------------------------------
Summary: WebHdfs compatibility broken between 2.2 and 1.x / 23.x
Key: HDFS-5449
URL: https://issues.apache.org/jira/browse/HDFS-5449
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Kihwal Lee
Priority: Blocker
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.
