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

             Summary: Remove the workaround to handle missing UGI.loginUserFromSubject
                 Key: STORM-2563
                 URL: https://issues.apache.org/jira/browse/STORM-2563
             Project: Apache Storm
          Issue Type: Bug
            Reporter: Arun Mahadevan
            Assignee: Arun Mahadevan


https://github.com/apache/storm/blob/master/storm-client/src/jvm/org/apache/storm/security/auth/kerberos/AutoTGT.java#L225
The "userCons.setAccessible(true)" invokes constructor of a package private class bypassing the Java access control checks and raising red flags in our internal security scans.

The "loginUserFromSubject(Subject subject)" has been added to UGI (https://issues.apache.org/jira/browse/HADOOP-10164) and available since Hadoop version 2.3 released over three years ago (http://hadoop.apache.org/releases.html).

 
I think the workaround is no longer required since the case will not happen when using hadoop-common versions >= 2.3
