> We have a lot of HiveSever2 servers deployed on production environment (about
> 10 nodes).
> However, if we want to change configuration or add patches, we would have to
> restart all of them one by one. So all the Hive Sql job running on the server
> will be defeated, and there may be some mistakes come up on the jdbc client
> occasionally.
> In the proposed changes, planning to add Graceful Shutdown HiveSever2 method
> to avoid affecting the production environment jobs
