Akira Ajisaka updated YARN-7450:
--------------------------------
Target Version/s: 2.9.3 (was: 2.9.2)
> ATS Client should retry on intermittent Kerberos issues.
> --------------------------------------------------------
>
> Key: YARN-7450
> URL: https://issues.apache.org/jira/browse/YARN-7450
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: ATSv2
> Affects Versions: 2.7.3
> Environment: Hadoop-2.7.3
> Reporter: Ravi Prakash
> Priority: Major
>
> We saw a stack trace (posted in the first comment) in the ResourceManager
> logs for the TimelineClientImpl not being able to relogin from keytab.
> I'm guessing there was an intermittent issue that failed the kerberos relogin
> from keytab. However, I'm assuming this was *not* retried because I only saw
> one instance of this stack trace. I propose that this operation should have
> been retried.
> It seems, this caused events at the ResourceManager to queue up and
> eventually stop responding to even basic {{yarn application -list}} commands.
