> HIVE-18281 added active-passive HA. There might be a administrative need to trigger a manual failover of HS2 Active server. Add command line tool to view list of all HS2 instances and trigger manual failover (only under force mode). The clients currently connected to active HS2 will be closed. In future, more options to existing clients connections can be handled via configs/options (like wait until timeout, wait until current sessions are closed etc.)
