Subject [jira] [Commented] (HBASE-8099) ReplicationZookeeper.copyQueuesFromRSUsingMulti should not return any queues if it failed to execute.
Date Thu, 14 Mar 2013 15:34:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8099?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13602348#comment-13602348

Lars Hofhansl commented on HBASE-8099:
--------------------------------------

That's fine I think. It's only an empty map (a few dozen bytes), and it's only if there something
to failover. It's just easier to read (IMHO) if you prefer the other approach that's fine.

By the same logic we the Random could also be per failover worker, although the Random constructor
does increment an AtomicLong.

Let's get this in soon, so I can spin the next RC.

> We just ran into an interesting scenario. We restarted a cluster that was setup as a
replication source.
> The stop went cleanly.
> Upon restart *all* regionservers aborted within a few seconds with variations of these
