HA: HDFS clients must handle namenode failover and switch over to the new active namenode.
------------------------------------------------------------------------------------------

                 Key: HDFS-1973
                 URL: https://issues.apache.org/jira/browse/HDFS-1973
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Suresh Srinivas


During failover, a client must detect the current active namenode failure and switch over to the new active namenode. The switch over might make use of IP failover or some thing more elaborate such as zookeeper to discover the new active.
