>
> * Test creates 3 node cluster (master + 2 RS) and creates 3 tables with 1 
> region each.
> * It then takes a snapshot of region assignments
> * Shuts down the cluster and restarts with 4 nodes (2 RS on same ports, 1 RS 
> on port where master was running previously and master on new port)
> * Takes snapshot of region assignments
> * Expected behavior is regions will be retained on RS with appropriate ports
> Debugging done so far shows that, when cluster is restarted meta is loaded 
> but meta has old entries (though the ports are same for RSs, start timestamps 
> are different). AssignmentManager#processofflineServersWithOnlineRegions() 
> finds that old RS with different timestamps are not online even though 
> regions assigned to them are online; triggering submitting SCP for each those 
> RSs. Subprocedure AssignProcedure of SCP has forceNewPlan set to true. Which 
> triggers re-assignment of regions.
