Subject [jira] [Created] (HDFS-4064) JNI-based user-group mapping modules can be too chatty on lookup failures
Date Tue, 16 Oct 2012 14:51:02 GMT
Kihwal Lee created HDFS-4064:
--------------------------------

             Summary: JNI-based user-group mapping modules can be too chatty on lookup failures
                 Key: HDFS-4064
                 URL: https://issues.apache.org/jira/browse/HDFS-4064
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: security
    Affects Versions: 3.0.0, 2.0.3-alpha, 0.23.5
            Reporter: Kihwal Lee
            Assignee: Kihwal Lee


On a user/group lookup failure, JniBasedUnixGroupsMapping and JniBasedUnixGroupsNetgroupMapping
are logging the
full stack trace at WARN level.  Since the caller of these methods is already logging errors,
this is not needed.  In branch-1, just one line is logged, so we don't need this change there.
