> To support work-preserving NM restart we need to recover the state of the 
> containers when the nodemanager went down.  This includes informing the RM of 
> containers that have exited in the interim and a strategy for dealing with 
> the exit codes from those containers along with how to reacquire the active 
> containers and determine their exit codes when they terminate.  The state of 
> finished containers also needs to be recovered.
