Subject [jira] [Commented] (MAPREDUCE-6571) JobEndNotification info logs are missing in AM container syslog
Date Mon, 05 Dec 2016 22:43:58 GMT

Robert Kanter commented on MAPREDUCE-6571:
------------------------------------------

+1 LGTM  There's a shutdown hook that already does this, so the log should still get cleanly
closed.

> JobEndNotification logs are not written by MRAppMaster and JobEndNotifier classes even
though Log.info is present. The reason was  MRAppMaster.this.stop() has been called before
the JobEndNotification and hence somewhere during the stop log appenders also made null.
> AM container syslog is not having below logs from JobEndNotifier
>    Job end notification trying + urlToNotify
>    Job end notification to + urlToNotify + succeeded / failed
