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

             Summary: HADOOP-10211 change for comma-separated list of QOP values broke backwards-compatibility with existing configs.
                 Key: HADOOP-10391
                 URL: https://issues.apache.org/jira/browse/HADOOP-10391
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 2.4.0
            Reporter: Chris Nauroth
            Priority: Blocker


HADOOP-10211 changed parsing of QOP values to support a comma-separated list.  This change accidentally broke backwards-compatibility with existing configs.  Previously, an unrecognized value caused it to default to authentication.  Now, an unrecognized value causes {{IllegalArgumentException}}.  Some deployments had been using a value of "none" in insecure clusters, so the change would break those existing deployments.
