Returns true if no current reconfiguration too. > ** Returns false otherwise > * Listen planned assignments key. On any updates: check if the current node > is a group leader and if yes: > ** Call cancelReconfiguration and if it returns false - do nothing > ** If true - put received planned list of peers to pending assignments in > metastore > * Also, onLeaderElected() listener must be updated with the similar logic > Then, all needed actions must be started by the further logic on event about > pending assignments update. -- This message was sent by Atlassian Jira (v8.20.1#820001)
