> Saw a warning message stating "trying to get DT with no secret manager 
> running".
> The isAllowedDelegationTokenOp() check call is questionably faulty, as per 
> https://issues.apache.org/jira/browse/HADOOP-9461. Since HADOOP-9461 is 
> potentially incompatible, I'm adding this minor check here to limit spurious 
> / scary warnings
