[jira] [Created] (YARN-3678) DelayedProcessKiller may kill other process other than container

gu-chi created YARN-3678:
----------------------------

             Summary: DelayedProcessKiller may kill other process other than container
                 Key: YARN-3678
                 URL: https://issues.apache.org/jira/browse/YARN-3678
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.6.0
            Reporter: gu-chi
            Priority: Critical


Suppose one container finished, then it will do clean up, the PID file still exist and will trigger once singalContainer, this will kill the process with the pid in PID file, but as container already finished, so this PID may be occupied by other process, this may cause serious issue.
As I know, my NM was killed unexpectedly, what I described can be the cause. Even rarely occur.
