Steve Rowe commented on SOLR-9386:
----------------------------------
bq. Steve Rowe, in newer ZK versions, standalone servers no longer require a
myid file. We shouldn't need to handle that any more. I can't locate the
ZOOKEEPER issue where that was changed, so I do not know what version made our
standalone config work, but I'm pretty sure that 3.4.8 had it.
I looked at the {{QuorumPeerConfig.parseConfiguration()}} code, and as you say,
the existence of a {{myid}} file is only checked for when the number of servers
is greater than one.
However, there is other code that enables Solr's embedded ZK to participate in
a quorum, so I think removing code that allows that would be a mistake. I
haven't tested setting up a quorum exclusively with embedded ZK in multiple
Solr nodes, but I assume that's possible.
