Subject [jira] [Created] (HDFS-3133) Add support for DFS upgrade with HA enabled
Date Fri, 23 Mar 2012 20:07:28 GMT
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.
