> As described in YARN-128, phase 1 of RM restart puts in place mechanisms to save application state and read them back after restart. Upon restart, the NM's are asked to reboot and the previously running AM's are restarted.
> After this is done, RM HA and work preserving restart can continue in parallel. For more details please refer to the design document in YARN-128
