[jira] [Created] (HADOOP-18138) UserGroupInformation shouldn't log exception

Chao Sun created HADOOP-18138:
---------------------------------

             Summary: UserGroupInformation shouldn't log exception 
                 Key: HADOOP-18138
                 URL: https://issues.apache.org/jira/browse/HADOOP-18138
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Chao Sun
            Assignee: Chao Sun


In {{UserGroupInformation.doAs}}, we currently create a new {{Exception}} and log it in {{LOG.debug}}. This doesn't look necessary:
{code}
      if (LOG.isDebugEnabled()) {
        LOG.debug("PrivilegedAction [as: {}][action: {}]", this, action,
            new Exception());
      }
{code}
