> When a cluster is fully shutdown and then started up again with hbase.master.startup.retainassign
set to true, I noticed that the assignments are not retained. Upon digging, it seems like
HBASE-10101 made a change due to which the server holding the META previously is added to
dead-servers (in _HMaster.assignMeta_). Later on, this makes the AssignmentManager think that
the master recovered from a failure as opposed to a fresh cluster start (the ServerManager.deadServers
list is not empty in the check within 
> _AssignmentManager.processDeadServersAndRegionsInTransition_)
