[jira] [Reopened] (SOLR-8075) Leader Initiated Recovery should not stop a leader that participated in an election with all of it's replicas from becoming a valid leader.

Mark Miller reopened SOLR-8075:
-------------------------------

There appears to be some race or something here. We need to turn off LIR *before* we try and publish ACTIVE upon becoming the leader. The test must only pass because somehow the check beats the ACTIVE publish or something.

> Currently, because of SOLR-8069, all the replicas in a shard can be put into LIR.
> If you restart such a shard, the valid leader will will win the election and sync with the shard and then be blocked from registering as ACTIVE because it is in LIR.
> I think that is a little wonky because I don't think it even tries another candidate because the leader that cannot publish ACTIVE does not have it's election canceled.
> While SOLR-8069 should prevent this situation, we should add logic to allow a leader that can sync with it's full shard to become leader and publish ACTIVE regardless of LIR.
