Jason Lowe updated YARN-1337:
-----------------------------
Description: 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. (was:

Summary: Recover containers upon nodemanager restart (was: Recover
