-----------------------------------

             Summary: Election timeout when no replicas are qualified to become leader
                 Key: SOLR-12051
                 URL: https://issues.apache.org/jira/browse/SOLR-12051
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Cao Manh Dat
            Assignee: Cao Manh Dat


After SOLR-12011 get committed, we can lead into the case when no active replicas are qualified to become the leader. The only 2 solutions for users in this case are
 * Using FORCE_LEADER API
 * Bring back the old leader

This ticket will introduce a leader election timeout so current active replicas can ignore the lost updates and go ahead to become the leader. I think it will be better and not confuse users by reusing {{leaderVoteWait}} (the current usage of {{leaderVoteWait}} for waiting replicas come up before leader election is no longer needed)
