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.
