Jun Gong reassigned YARN-5154:
------------------------------
Assignee: Jun Gong
> DelayedProcessKiller can kill the wrong process if pid is recycled
> ------------------------------------------------------------------
>
> Key: YARN-5154
> URL: https://issues.apache.org/jira/browse/YARN-5154
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.8.0, 2.7.2, 2.6.4
> Reporter: Jason Lowe
> Assignee: Jun Gong
>
> YARN-4459 reduced the chance of the container-executor accidentally killing
> the wrong process when pids are recycled, but it can still occur. We should
> improve the DelayedProcessKiller to cancel the timer if the container exits
> between the deliverly of the two signals and/or implement some sanity checks
> in the executor just before delivering the signal to try to avoid killing the
> wrong thing.
