[jira] [Created] (ZOOKEEPER-3450) Allow Quorum Leader to Register with Another Quorum

David Mollitor created ZOOKEEPER-3450:
-----------------------------------------

             Summary: Allow Quorum Leader to Register with Another Quorum
                 Key: ZOOKEEPER-3450
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3450
             Project: ZooKeeper
          Issue Type: Sub-task
          Components: server
            Reporter: David Mollitor


When a ZK instance within a quorum is elected leader, add a feature that registers all the servers within the quorum with another ZK quorum.

The idea is ultimately that all quorums within an environment register with a single global quorum so that clients can discover the service-specific quorums.

{code:Plain Text}
/zk/register/<service>/quorum{host1,host2,host3}

/zk/register/hbase/quorum{host1,host2,host3}
/zk/register/hdfs/quorum{host1,host2,host3}
/zk/register/yarn/quorum{host1,host2,host3}
{code}

Note that a single quorum should be able to register (be responsible for) several services.
