[jira] [Commented] (YARN-5487) Can't kill nodemanager process when
running in the foreground
[ https://issues.apache.org/jira/browse/YARN-5487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15416449#comment-15416449 ]
Kai Sasaki commented on YARN-5487:
----------------------------------
[~aw]
When I tried to reproduce with Hadoop 2.7.2 and trunk, NodeManager can be shutdown correctly with ctrl-c.
How can you reproduce this?
{code}
16/08/11 03:09:13 INFO nodemanager.NodeManager: SHUTDOWN_MSG:

> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.7.2
> Reporter: Allen Wittenauer
> Labels: regression

> It looks like there is a misconfigured signal handler somewhere in the mix. Hitting ctrl-c results in this message:
> 16/08/08 20:26:37 ERROR nodemanager.NodeManager: RECEIVED SIGNAL 2: SIGINT
> ... which is then summarily ignored.
