[jira] [Created] (YARN-4834) ProcfsBasedProcessTree doesn't track daemonized processes

Nathan Roberts created YARN-4834:
------------------------------------

             Summary: ProcfsBasedProcessTree doesn't track daemonized processes
                 Key: YARN-4834
                 URL: https://issues.apache.org/jira/browse/YARN-4834
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.7.2, 3.0.0
            Reporter: Nathan Roberts
            Assignee: Nathan Roberts


Currently the algorithm uses ppid from /proc/<pid>/stat which can be 1 if a child process has daemonized itself. This causes potentially large processes from not being monitored. 

session id might be a better choice since that's what we use to signal the container during teardown.
