Summary: Decommissioned NM leaves orphaned containers
Key: YARN-7751
URL: https://issues.apache.org/jira/browse/YARN-7751
Project: Hadoop YARN
Issue Type: Bug
Reporter: Tao Yang
Recently we found some orphaned containers running on a decommissioned NM in
our production cluster. The beginning of this problem is PCIE error of this
node, one of local directories is not writable so that containers whose pid
files located on it can't be cleanup successfully, after a few moments, NM
changed to DECOMMISSIONED state and exited.
Corresponding logs in NM:
