------------------------------
Issue Type: Sub-task (was: Bug)
Parent: YARN-149
> cancelDelegationToken should survive RM failover
> ------------------------------------------------

> The problem of cancelDelegationToken is a bit different from that of
> renewDelegationToken. Say when the cancel op is almost done
> (AbstractDelegationTokenSecretManager removes the DT from its cache, and
> RMStateStore removes it form FS/ZK), and just before returning response to
> the client, RM failover. The new AbstractDelegationTokenSecretManager cache
> will not have the DT, and the following cancelDelegationToken will fail at
> {code}
> if (info == null) {
> throw new InvalidToken("Token not found");
> }
> {code}
> in AbstractDelegationTokenSecretManager#cancelToken
