 Review comment:
   I don't think this behavior is needed. There's no reason to expect the keytab *won't* be on the worker nodes. If the user wants to use a delegation token, they can create one and pass it in. This auto-allocation of delegation tokens without user explicit acknowledgement is probably a bit dangerous anyway and may not be what users intend.
   
   If `getClientInfo` was added solely to support this feature, it is probably not needed.
