I suppose the problem could be in zkHelper.copyQueuesFromRSUsingMulti(rsZnode) as called from ReplicationSourceManager.NodeFailoverWorker.run(). copyQueuesFromRSUsingMulti will return the queues it read even when the multi operation failed (because another RS managed to execute it first).

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 errors: http://pastebin.com/3iQVuBqS This is scary! -- Lars
