SOLR-12051: Update upgrade notes
> 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: Sub-task
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Cao Manh Dat
> Assignee: Cao Manh Dat
> Priority: Major
> Fix For: 7.3, master (8.0)

> Attachments: SOLR-12051.patch
>
>
> 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)
