     [ https://issues.apache.org/jira/browse/YARN-4549?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jason Lowe resolved YARN-4549.
------------------------------
    Resolution: Invalid

Glad to hear the cause was found!  Be sure to check that the NM state store is also stored outside of /tmp, or it too can become a victim of tmpwatch.

>                 Key: YARN-4549
>                 URL: https://issues.apache.org/jira/browse/YARN-4549
>             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.

> 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.
