Auto-HA: automatically scope znode by nameservice ID
----------------------------------------------------

                 Key: HADOOP-8246
                 URL: https://issues.apache.org/jira/browse/HADOOP-8246
             Project: Hadoop Common
          Issue Type: Improvement
          Components: auto-failover, ha
    Affects Versions: Auto Failover (HDFS-3042)
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


Talking to some folks who work on operations/deployment, they pointed out that it would make
sense to automatically include the nameservice ID in the base znode used for automatic failover.
For example, even though the "root znode" is "/hadoop-ha", we should put the znodes for a
nameservice "my-ha-cluster" within "/hadoop-ha/my-ha-cluster". This allows federated setups
to work with no additional configuration.
