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

             Summary: Update the auth_to_local rules documentation in hadoop documentation
                 Key: HDFS-12849
                 URL: https://issues.apache.org/jira/browse/HDFS-12849
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Bharat Viswanadham
            Assignee: Bharat Viswanadham


<property>
  <name>hadoop.security.auth_to_local</name>
  <value>
    RULE:[2:$1@$0](nn/.*@.*REALM.TLD)s/.*/hdfs/
    RULE:[2:$1@$0](jn/.*@.*REALM.TLD)s/.*/hdfs/
    RULE:[2:$1@$0](dn/.*@.*REALM.TLD)s/.*/hdfs/
    RULE:[2:$1@$0](nm/.*@.*REALM.TLD)s/.*/yarn/
    RULE:[2:$1@$0](rm/.*@.*REALM.TLD)s/.*/yarn/
    RULE:[2:$1@$0](jhs/.*@.*REALM.TLD)s/.*/mapred/
    DEFAULT
  </value>
</property>
 
As the first part is translating to nn@REALM, so the expression is not matching, and the replacement is not happening.
