I don’t think you’ll find an official EOL announcement. Here’s a guide, but do note the phrase “on demand” for minor releases. You should interpret “on demand” as when the developers feel the issues in the current point-release code base are numerous enough or critical enough to warrant the effort

The problem with Solr related to use TLS with ZK is the following: * 3.5.5 seem to only support tls certificate authentication together with TLS . Solr support es only digest and Kerberos authentication. However, I have to check in the ZK jiras if this has changed with higher ZK versions * quorum

Good to hear and thanks for reporting back. The other thing ZK 3.5 allegedly makes easier is dynamically reconfiguring the ensemble. Again, haven’t personally tried it but I’d be cautious about that since Solr won’t be using the 3.5 jars and just dropping the 3.5 jars in for Solr to use would be t

Ah, understood. It always looks better to be able to say “I’ve tried it and this is what I found” than “Uh, I’ll have to get back to you on that” ;) I’ve occasionally been able to assuage clients like that by pointing out that often, especially with Open Source, announcing end of support is often

Thanks, Erick. I'll give it a go this weekend and see how it behaves. I'll report back so there's a record of my attempts in case anyone else ends up asking the same question. Some of our customers get a bit nervous when software goes out of support, even if it works fine, so I try to be prepared

All it means is that there won’t be upgrades/improvements to ZK, 3.4 will still run. So there’s no need to move to 3.5 independent of upgrading Solr just because that version of ZK is unsupported going forward. I haven’t personally tried to run 3.5 against an earlier version, but one thing you’ll

Hey folks, The ZK team just announced that they're dropping 3.4 support as of the 1st of June, 2020. What does this mean for those of us still on Solr < 8.2? From what I can tell, ZooKeeper 3.5+ does not work with older Solr versions. Has anyone managed to get a 3.5+ to work with Solr 7 at all?
