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. -- This message was sent by Atlassian JIRA (v6.1#6144)
