Subject [jira] [Commented] (HIVE-4778) hive.server2.authentication CUSTOM not working
Date Fri, 30 Aug 2013 23:53:52 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4778?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13755275#comment-13755275
] 

Mikhail Antonov commented on HIVE-4778:
---------------------------------------

I also encountered the same issue today, and obviously, simplest workaround is to use the
following in hive-site.xml:

<property>
    <!--<name>hive.server2.custom.authentication.class</name>-->
    <name>HIVE_SERVER2_CUSTOM_AUTHENTICATION_CLASS</name>
    <value>com.zettaset.hive.security.auth.ZtsHiveAuthenticationProvider</value>
</property>

That works.
