> Slow delegation token renewal can severely prolong RM recovery
> --------------------------------------------------------------
>
> Key: YARN-4041
> URL: https://issues.apache.org/jira/browse/YARN-4041
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.6.0
> Reporter: Jason Lowe
> Assignee: Sunil G
> Attachments: 0001-YARN-4041.patch, 0002-YARN-4041.patch,
> 0003-YARN-4041.patch, 0004-YARN-4041.patch
>
>
> When the RM does a work-preserving restart it synchronously tries to renew
> delegation tokens for every active application. If a token server happens to
> be down or is running slow and a lot of the active apps were using tokens
> from that server then it can have a huge impact on the time it takes the RM
> to process the restart.
