Timothy Potter commented on SOLR-6235:
--------------------------------------
We have a similar issue where a replica attempting to be the leader needs to
wait a while to see other replicas before declaring itself the leader, see
ElectionContext around line 200:
int leaderVoteWait = cc.getZkController().getLeaderVoteWait();
if (!weAreReplacement) {
waitForReplicasToComeUp(weAreReplacement, leaderVoteWait);
}
So one quick idea might be to have the code that checks if it's in LIR see if
all replicas are in LIR and if so, wait out the leaderVoteWait period and check
again. If all are still in LIR, then move on with becoming the leader (in the
spirit of availability).
