Zookeeper 3.4.12 with Solr 6.6.2?
Is anybody running Zookeeper 3.4.12 with Solr 6.6.2? Is that a recommended combination? Not recommended?

We have 3.4.10 and have *tested* at a functional level 6.6.2. So far it
works. We have not done any stress/load testing. But would have to do this
prior to release.

Solr 6.6.2 shipped with ZK 3.4.10, which the ZK project released
2017-Mar-30.
I asked the zk mailing list about any gotchas they're aware of when
running mismatched versions, assuming the server is running a newer
version than the client. They replied with a document discussing their
backward compatibility goals (scroll to the end):
https://cwiki.apache.org/confluence/display/ZOOKEEPER/ReleaseManagement
Solr 4.0.0 (the first stable version with Cloud mode) shipped with ZK
3.3.6. In 4.1.0, that was upgraded to ZK 3.4.5. Solr 7.4.0 will most
likely ship with ZK 3.4.12. (SOLR-12346)
ALL versions of SolrCloud should work with 3.4.12 on the ZK server side.
If you upgrade your ZK servers to the 3.5 beta, then no guarantees can
be made for Solr 4.0, but 4.1 and later should work.
Thanks,
Shawn
