    • Sprint 2 - March 11 - April 3

    Description

      We have a number of bugs due to erlang global facility or related issue of not being able to spawn new master quickly. I.e.:

      • MB-7282 (erlang's global naming facility apparently drops globally registered service with actual service still alive (was: impossible to change settings/autoFailover after rebalance))
      • MB-7168 [Doc'd 2.2.0] failover of node that's completely down is still not quick (was: Rebalance exited with reason {not_all_nodes_are_ready_yet after failover node)
      • MB-8682 start rebalance request is hunging sometimes (looks like another global facility issue)
      • MB-5622 Crash of master node may lead to autofailover in 2 minutes instead of configured shorter autofailover period or similarly slow manual failover

      By getting us off global, we will fix all this issues.
