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]([email protected])s/.*/mapred/{code}
