             Summary: Add detailed logging in KMS log for the authentication failure of proxy user
                 Key: HADOOP-13526
                 URL: https://issues.apache.org/jira/browse/HADOOP-13526
             Project: Hadoop Common
          Issue Type: Bug
          Components: kms
         Environment: RHEL
            Reporter: Suraj Acharya
            Priority: Minor


Problem :
User A was not able to write a file to HDFS Encryption Zone. It was resolved by adding proxy user A in kms-site.xml
However, the logs showed :
{code}2016-08-10 19:32:08,954 DEBUG org.apache.hadoop.security.authentication.server.AuthenticationFilter: Request https://vm.example.com:16000/kms/v1/keyversion/aMxsSSKmMEzINTIrKURpFJgHnZxiOvsT9L1nMpbUoGu/_eek?eek_op=decrypt&doAs=userb&user.name=usera user [usera] authenticated{code}

Possible Solution :
So the message which says the user was successfully authenticated comes from {{AuthenticationFilter.java}}. However, when the filter on {{DelegationTokenAuthenticationFilter}} is called it hits an exception there and there is no log message there. This leads to the confusion that we have had a success while the exception happens in the next class.
