-----------------------------------
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.
