Jeff Zhang commented on TEZ-2311:
---------------------------------
Upload a new patch.
Actually it is not necessary to call shutdown explicitly.
* for non-session mode, it would shutdown itself after the dag is
recovered(finished)
* for session mode, just set sessionStopped as true will cause AM shutdown
after dag is recovered(finished)
bq. Also, I don't see "sessionStopped" set to false anywhere.
Not sure what you mean, it should be not necessary to set it to false.
> AM can hang if kill received while recovering from previous attempt
