Subject [jira] [Created] (HBASE-11629) Operational concerns for Replication should call out ZooKeeper
Date Thu, 31 Jul 2014 15:46:39 GMT
Sean Busbey created HBASE-11629:

             Summary: Operational concerns for Replication should call out ZooKeeper
                 Key: HBASE-11629
                 URL: https://issues.apache.org/jira/browse/HBASE-11629
             Project: HBase
          Issue Type: Bug
          Components: documentation, Replication
            Reporter: Sean Busbey

Our [design invariants state that ZooKeeper data is safe to delete|http://hbase.apache.org/book/developing.html#design.invariants.zk.data].
However, [replication only stores its data in zookeeper|http://hbase.apache.org/replication.html#Replication_Zookeeper_State].

This can lead to operators accidentally disabling their replication set up while attempting
to recover from an unrelated issue by clearing the zk state.

We should update the [operational concerns section on replication|http://hbase.apache.org/book/cluster_replication.html]
to call out that the /hbase/replication tree should not be deleted. We should probably also
add a warning to the set up steps.
