             Summary: Investigate how to access permanent function with restarting HS2 if load balancer is configured
                 Key: HIVE-14788
                 URL: https://issues.apache.org/jira/browse/HIVE-14788
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
            Reporter: Aihua Xu
            Assignee: Aihua Xu


When load balancer is configured for multiple HS2 servers, seems we need to restart each HS2 server to get permanent function to work. Since the command "reload function" issued from the client to refresh the global registry may is not targeted to a specific HS2 server, some servers may not get refreshed and ClassNotFoundException may be thrown later.

Investigate if it's an issue and a good solution for it.
