--------------------------------
Thanks [~jlowe], agree that a asynchronous state store will always lead to
inconsistent and hard to fix. make state store first seems a reasonable way.
> Add a percentage-node threshold for RM to wait for new allocations after
> restart/failover

> This is the remaining part of YARN-2001 - to halt allocations after restart
> till x% of nodes sync back with the RM. This is useful for avoiding bad
> scheduling during the time the nodes are still joining back after a
> restart/failover.
