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

Thanks for the suggested solution. The auth_to_local rule mapping is part of hadoop implementation.

> In a kerberized HS2 with LDAP authentication enabled, LDAP user usually logs in using
username in form of username@domain in LDAP multi-domain case. But it fails if the domain
was not in the Hadoop auth_to_local mapping rule, the error is as following:
> {code}
> Caused by: org.apache.hadoop.security.authentication.util.KerberosName$NoMatchingRule:
No rules applied to ctang@mydomain.com
> at org.apache.hadoop.security.authentication.util.KerberosName.getShortName(KerberosName.java:389)
> at org.apache.hadoop.security.User.<init>(User.java:48)
> {code}
