Subject [jira] [Commented] (HBASE-16087) Replication shouldn't start on a master if if only hosts system tables
Date Thu, 30 Jun 2016 18:00:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16087?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15357571#comment-15357571
] 

Gary Helmling commented on HBASE-16087:
---------------------------------------

The propagation of updates to the caches is triggered by postPut() and postDelete() hooks
on the acl table, so replicating acl changes should not prevent the caches from being updated.

That said, I would not normally replicate the acl tables as there are plenty of cases where
you would not want the exact same permissions scheme applied between the replication source
and target.

> System tables aren't replicated so we shouldn't start up a replication master if there
are no user tables on the master.
