> Any uncaught exception at DelegationTokenRenewer.RenewalTimerTask#run causes all subsequent yarn apps to fail with java.lang.IllegalStateException: Timer already cancelled
> One such NPE is thrown when DelegationTokenRenewer.RenewalTimerTask#run invokes DelegationTokenRenewer#removeFailedDelegationToken that tries to remove token from the "DelegationTokenRenewer#appTokens" for an applicationId.
> If DelegationTokenRenewer#appTokens map didn’t have the <ApplicationId, Set<DelegationTokenToRenew>> entry while token (DelegationTokenToRenew) had the reference to the applicationId, then NPE is thrown leading to "Timer already cancelled"
