> 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.
