> Add a hierarchy into the ZKRMStateStore for delegation token znodes to
> prevent jute buffer overflow
> ---------------------------------------------------------------------------------------------------
>
> Key: YARN-7262
> URL: https://issues.apache.org/jira/browse/YARN-7262
> Project: Hadoop YARN
> Issue Type: Improvement
> Affects Versions: 2.6.0
> Reporter: Robert Kanter
> Assignee: Robert Kanter
> Attachments: YARN-7262.001.patch, YARN-7262.002.patch,
> YARN-7262.003.patch, YARN-7262.003.patch
>
>
> We've seen users who are running into a problem where the RM is storing so
> many delegation tokens in the {{ZKRMStateStore}} that the _listing_ of those
> znodes is higher than the jute buffer. This is fine during operations, but
> becomes a problem on a fail over because the RM will try to read in all of
> the token znodes (i.e. call {{getChildren}} on the parent znode). This is
> particularly bad because everything appears to be okay, but then if a
> failover occurs you end up with no active RMs.
> There was a similar problem with the Yarn application data that was fixed in
> YARN-2962 by adding a (configurable) hierarchy of znodes so the RM could pull
> subchildren without overflowing the jute buffer (though it's off by default).
> We should add a hierarchy similar to that of YARN-2962, but for the
> delegation token znodes.
