Subject [jira] [Updated] (ZOOKEEPER-3450) Allow Quorum Leader to Register with Another Quorum
Date Mon, 01 Jul 2019 14:00:07 GMT

     [ https://issues.apache.org/jira/browse/ZOOKEEPER-3450?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

David Mollitor updated ZOOKEEPER-3450:
--------------------------------------
    Description: 
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:none}
/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.
