----------------------------------
Hi, [~rayman7718], thank you for the conf, I have set these, container is not
exit when restarting NM by supervisor.
Now,I encountered a different situation.,I set
yarn.nodemanager.delete.debug-delay-sec=600s, through the Debug log, I get the
following information
1 -> Begin, only one container1 of app1 is running on NM1
2 -> After a while, when container1 is finished, app1 dir (such as
/xxx/nmPrivate/app1) will to be cleanup after 600s
(After about 10s, I restart NM1, I don't know if this has any effect on the
result
3 -> After about 300s, container2 of app1 is allocated on NM1, and file
/xxx/nmPrivae/app1/container2/container2.pid is crated
4 -> After the end of container1 600s, the file
/xxx/nmPrivae/app1/container2/container2.pid is deleted
the container2 never exit, cleanupContainer got stuck, ContainerManagerImpl got
stuck, NM got stuck
> Deletion Taks will be picked up to delete running containers

> Project: Hadoop YARN
> Issue Type: Bug
> Components: applications
> Affects Versions: 2.9.1
> Reporter: Sihai Ke
> Priority: Major
>
> I suspect there is a bug in Yarn deletion task service, below is my repo
> steps:
> # First let's set yarn.nodemanager.delete.debug-delay-sec=3600, that means
> when the app finished, the Binary/container folder will be deleted after 3600
> seconds.
> # when the application App1 (long running service) is running on machine
> machine1, and machine1 shutdown, ContainerManagerImpl#serviceStop() will be
> called -> ContainerManagerImpl#cleanUpApplicationsOnNMShutDown, and
> ApplicationFinishEvent will be sent, and then some delection tasks will be
> created, but be stored in DB and will be picked up to execute 3600 seconds.
> # 100 seconds later, machine1 comes back, and the same app is assigned to
> run this this machine, container created and works well.
> # then deleting task created in step 2 will be picked up to delete
> containers created in step 3 later.
