    Description

      Setting a config on master enables the multicast feature where master will udp broadcast to all listeners – clients – when it learns of dead servers. Clients that get notification react by redoing their region locations cache which helps them be more response when servers die. This feature has been around for years but probably goes unknown since no mention in documentation. This issue is about adding a basic paragraph on what it does and how to use it. The original issue has a nice release note that could serve as the basis for this paragraph. See HBASE-7590
