Add support for DFS upgrade with HA enabled -------------------------------------------
Key: HDFS-3133 URL: https://issues.apache.org/jira/browse/HDFS-3133 Project: Hadoop HDFS Issue Type: Improvement Components: ha, name-node Affects Versions: 0.24.0 Reporter: Aaron T. Myers For the first implementation of HA NameNode, we punted on allowing DFS upgrade with HA enabled, which makes doing a DFS upgrade on an HA-enabled cluster quite cumbersome and error-prone. We should add better support for this. -- This message is automatically generated by JIRA.
