      Description

      A secure webhdfs client will receive an exception from a non-secure NN. For a NN in non-secure mode, FSNamesystem#getDelegationToken will return "null" to indicate no token is required. Hdfs will send back the null to the client, but webhdfs uses DelegationTokenSecretManager.createCredentials which instead throws an exception.
