Is it possible to stop gracefully master (not by kill -9 ) without sending shutdown messages to region serves? Currently we are testing 2 masters architecture with failover and in this configuration it is really undesirable to shutdown whole cluster when we want only to perform only some updates on that node. Thanks, Michal --001485e8e7399fc65604815fd5ff--
