> ReplicationSource only calls ReplicationSourceManager.logPositionAndCleanOldLogs if it
replicated something, meaning that a region server that doesn't host a region with replicable
edits will read through the logs but never report the position in zookeeper and won't clean
the processed hlogs. This happened on one cluster here and shutting down a region server took
a few minutes just to delete all the znodes.
