Description

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
