-----------------------------
Resolution: Duplicate
> Security related work for RM restart
> ------------------------------------
>
> Key: YARN-248
> URL: https://issues.apache.org/jira/browse/YARN-248
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: resourcemanager
> Reporter: Tom White
> Assignee: Bikas Saha
>
> On restart, the RM creates a new RMDelegationTokenSecretManager with fresh
> state. This will cause problems for Oozie jobs running on secure clusters
> since the delegation tokens stored in the job credentials (used by the Oozie
> launcher job to submit a job to the RM) will not be recognized by the RM, and
> recovery will fail.
