Review request for hive.
Bugs: HIVE-8916
https://issues.apache.org/jira/browse/HIVE-8916
Repository: hive-git
Description
-------
HIVE-8916 : Handle user@domain username under LDAP authentication
If LDAP is configured with multiple domains for authentication, users can be in
different domains.
Currently, LdapAuthenticationProviderImpl blindly appends the domain configured
"hive.server2.authentication.ldap.Domain" to the username, which limits user to
that domain. However, under multi-domain authentication, the username may
already include the domain (ex: u...@domain.foo.com). We should not append a
domain if one is already present.
Also, if username already includes the domain, rest of Hive and authorization
providers still expects the "short name" ("user" and not "u...@domain.foo.com")
for looking up privilege rules, etc. As such, any domain info in the username
should be stripped off.

Testing
-------
Configured HS2 for LDAP authentication:
<property>
<name>hive.server2.authentication</name>
<value>LDAP</value>
</property>
<property>
<name>hive.server2.authentication.ldap.url</name>
<value>ldap://foo.ldap.server.com</value>
</property>
<property>
<name>hive.server2.authentication.ldap.Domain</name>
<value>foo.ldap.domain.com</value>
</property>
Ran beeline with user names with and without ldap domain, in both cases
authentication works. Before the change, authentication failed if
domain was present in username:
beeline -u jdbc:hive2://localhost:10000 -n u...@foo.ldap.domain.com -p
TestPassword --debug
beeline -u jdbc:hive2://localhost:10000 -n user -p TestPassword --debug
Thanks,
