Hanisha Koneru commented on HADOOP-14229:
-----------------------------------------
[~boky01],
Verified that the current suggested settings for hadoop.security.auth_to_local
in
https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SecureMode.html
do not perform the intended action.
As you said, the command _hadoop kerbname jhs/[email protected]_ gives the
following result:
bq. Name: jhs/[email protected] to jhs/[email protected]
whereas, the intended result is:
bq. Name: jhs/[email protected] to mapred
The patch LGTM.
> hadoop.security.auth_to_local example is incorrect in the documentation

> 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}
