Alejandro Abdelnur commented on YARN-248:

Good point Tom, #ii would work for Hadoop-1 but for YARN we need a YARN generic approach.

> 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.
