stack commented on HBASE-3596:

+1 Seems fine though waiting is probably not always going to work.

> ReplicationSourceManager.transferQueues is running a little too fast at the moment and
this has the bad side effect of making us run into HBASE-2611 at almost every cluster restart.
The reason is that some servers might shut down faster than others so that the last RS that
are notified will at the same time see their friends dying, and will try to pick their queues.
What happens then is that they also get told to shutdown and might be able to close their
ZK session before the queue transfer process is completed, which is what 2611 is about.
> Currently the only to fix to that is to delete the lock znode by hand and bounce a region
server so that it picks up the queue on startup.
