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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
