    Description

      I tried to set the following property for auth_to_local property:

      "RULE:[2:$1]((n|d)n)s/.*/hdfs//

      but I got the following exception:

      Exception in thread "main" java.util.regex.PatternSyntaxException: Unclosed group near index 9
      (nn|dn|jn

      I found that this occurs because ruleParser in org.apache.hadoop.security.authentication.util.KerberosName excludes closing parentheses.

      I do not really see the value of excluding parentheses (do I miss something?) so I would remove this restriction to be able to use more regex functionalities.
