> This bug may be minor as it likely to happen in a single node setup.
> I restarted the RS holding META. The master tried assigning META using MetaSSH. But tried
this before the new RS came up.
> So as not region plan is found 
> {code}
>  if (plan == null) {
>         LOG.warn("Unable to determine a plan to assign " + region);
>         if (tomActivated){
>           this.timeoutMonitor.setAllRegionServersOffline(true);
>         } else {
>           regionStates.updateRegionState(region, RegionState.State.FAILED_OPEN);
>         }
>         return;
>       }
> {code}
> we just return without assigment.  And this being the META the small cluster just hangs.
