          Components: RM, yarn
            Reporter: Fengnan Li
            Assignee: Fengnan Li


We have seen multiple issues related with Yarn DelegationTokenRenewer, especially when namenodes
where the token was given had some issues (i.e. standby down). This component has become a
SPOF blocking all Yarn applications to be accepted.
