---------------------------------

Thanks for the good suggestion [~cnauroth]! Yes, I uploaded a new patch HDFS-9085.002.patch, which added a unit test to verify {{toString}}.

> Show renewer information in {{DelegationTokenIdentifier#toString}}. Currently 
> {{org.apache.hadoop.hdfs.security.token.delegation.DelegationTokenIdentifier}} didn't show the renewer information. It will be very useful to have renewer information to debug security related issue. Because the renewer will be filtered by "hadoop.security.auth_to_local", it will be helpful to show the real renewer info after applying the rules.
