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. -- This message was sent by Atlassian JIRA (v6.2#6252)
