-----------------------------------
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)
