Shalin Shekhar Mangar commented on SOLR-6235:
---------------------------------------------
bq. But iff not all known replicas are participating and you still want to
force a leader, that should be optional - I think it should default to false
though. I think the system should default to reasonable data safety in these
cases.
That's the same case as the leaderVoteWait situation and we do go ahead after
that amount of time even if all replicas aren't participating. Therefore, I
think that we should handle it the same way. But to help people who care about
consistency over availability, there should be a configurable property which
bans this auto-promotion completely.
In any case, we should switch to coreNodeName instead of coreName and open an
issue to improve the leader election part.
