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

thank you [~ctang.ma]

Looking at your patch

+        // KerberosName.getShorName can only be used for kerberos user, but not for the user
+        // logged in via other authentications such as LDAP
+        KerberosNameShim fullKerberosName = ShimLoader.getHadoopShims().getKerberosNameShim(userName);
+        ret = fullKerberosName.getShortName();
...

Is there any specific reason getShortName() can't be used for LDAP principals too?
Looking around for potential solutions for HIVE-15174

Thanks!

> 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}
