             Summary: Investigate how to access permanent function with 
restarting HS2 if load balancer is configured
                 Key: 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.
