Subject [jira] [Updated] (HDFS-9085) Show renewer information in DelegationTokenIdentifier#toString
Date Thu, 08 Oct 2015 17:55:27 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9085?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Chris Nauroth updated HDFS-9085:
        Hadoop Flags: Incompatible change,Reviewed
    Target Version/s: 3.0.0
         Component/s: security

Hello [~zxu].  Sorry for the delayed response.  I am +1 for a commit to trunk only, flagging
it as backwards-incompatible, and entering a release note that describes the change in output
for {{hdfs fetchdt --print}}.

Before we commit, do you think you can add a unit test to check the new {{toString}} output?

> 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.
