--------------------------------------------
Summary: Use onLeaderElected callback to register CMG leader
topology listeners
Key: IGNITE-17799
URL: https://issues.apache.org/jira/browse/IGNITE-17799
Project: Ignite
Issue Type: Improvement
Reporter: Aleksandr Polovtcev
Assignee: Aleksandr Polovtcev
{{ClusterManagementGroupManager}} does not support Raft leader change. When the
CMG leader is elected, it registers a topology listener to notify incoming
nodes about the CMG state. However, this is currently only done once during the
init phase, so if the leadership is lost after that, node join will not be
possible, because the new leader will not have the topology listener registered.
