Subject [jira] [Created] (HADOOP-14229) hadoop.security.auth_to_local example is incorrect in the documentation

Andras Bokor created HADOOP-14229:
-------------------------------------

             Summary: hadoop.security.auth_to_local example is incorrect in the documentation
                 Key: HADOOP-14229
                 URL: https://issues.apache.org/jira/browse/HADOOP-14229
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Andras Bokor
            Assignee: Andras Bokor
            Priority: Trivial


Let's see jhs as example:
{code}RULE:[2:$1@$0](jhs/.*@.*REALM.TLD)s/.*/mapred/{code}
That means principal has 2 components (jhs/myhost@REALM).
The second column converts this to jhs@REALM. So the regex will not match on this since regex
expects / in the principal.
I am not sure what was the original intend here so I suggest two solutions:
{code}RULE:[2:$1/$2@$0](jhs/.*@REALM.TLD)s/.*/mapred/{code}
or
{code}RULE:[2:$1@$0](jhs@REALM.TLD)s/.*/mapred/{code}
