             Summary: Integrate Ranger lookup JAAS configuration in 
ranger-admin plugin jar
                 Key: HAWQ-1493
                 URL: https://issues.apache.org/jira/browse/HAWQ-1493
             Project: Apache HAWQ
          Issue Type: Sub-task
          Components: Security
            Reporter: Hongxu Ma
            Assignee: Radar Lei
             Fix For: 2.3.0.0-incubating


For support ranger lookup a kerberized HAWQ, we modify java.security file and 
add a .java.login.config file into ranger account now.
But both of the two files are global, have influenced other program, so we need 
integrate the JAAS configuration in a private scope.

After investigation, `setProperty("java.security.auth.login.config")` in 
ranger-admin plugin code is a good solution.
