Aihua Xu commented on HIVE-11826:
---------------------------------

Sorry. I didn't upstream 0.13 but in CDH5.3.3 with Hive-0.13 which seems to have correct change.
Then upstream 0.13 will also have the same issue. I will update to use the newer version.

         if (useProxy) {
            clientUgi = UserGroupInformation.createProxyUser(
                endUser, UserGroupInformation.getLoginUser());
            // ensure that metastore user has privilege to impersonate the requesting user
            ProxyUsers.authorize(clientUgi,
                getRemoteAddress().getHostAddress(), null);
            remoteUser.set(clientUgi.getShortUserName());
            LOG.debug("Set remoteUser :" + remoteUser.get());

> With 'hadoop.proxyuser.hive.groups' configured in core-site.xml to certain groups, currently
if you run the job with a user not belonging to those groups, it won't fail to access metastore.
With old version hive 0.13, actually it fails properly. 
> Seems HadoopThriftAuthBridge20S.java correctly call ProxyUsers.authorize() while HadoopThriftAuthBridge23
doesn't.
