Danil Serdyuchenko commented on YARN-4549:
------------------------------------------

Yep, looks like we had tmpwatch delete all files older than 10 days. We have 
set the NM local-dirs to be outside of tmp. [~jlowe] thanks for your help. 

> Containers stuck in KILLING state

>             Project: Hadoop YARN
>          Issue Type: Bug
>    Affects Versions: 2.7.1
>            Reporter: Danil Serdyuchenko
>
> We are running samza 0.8 on YARN 2.7.1 with {{LinuxContainerExecutor}} as the 
> container-executor with cgroups configuration. Also we have NM recovery 
> enabled.
> We observe a lot of containers that get stuck in the KIILLING state after the 
> NM tries to kill them. The container remains running indefinitely, this 
> causes some duplication as new containers are brought up to replace them. 
> Looking through the logs NM can't seem to get the container PID.

> container_1448454866800_0023_01_000005. Waited for 2000 ms.
> {noformat}
> The PID files for containers in the KILLING state are missing, and a few 
> other container that have been in the RUNNING state for a few weeks are also 
> missing them.  We waren't able to consistently replicate this and hoping that 
> someone has come across this before.
