[jira] [Updated] (HADOOP-14229) hadoop.security.auth_to_local
example is incorrect in the documentation
[ https://issues.apache.org/jira/browse/HADOOP-14229?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andras Bokor updated HADOOP-14229:
----------------------------------
Description:
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.
My suggestion is
{code}RULE:[2:$1](jhs)s/.*/mapred/{code}
was:

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}
