The problem that led to ZK pulling 3.4.11 from download is only on the
server side -- the client usage inside Solr itself should have no
issues. If you do not use a separate ZK ensemble and have the server
running embedded in Solr, then that ZK server would experience the
bug, but it wouldn't actually cause anything to break.
Clarification to what I wrote before -- if the ZK server config for the
embedded server isn't changed from what ships with Solr, there shouldn't
be any breakage. If the config is changed, then the bug MIGHT be
encountered.
This is the bug:
https://issues.apache.org/jira/browse/ZOOKEEPER-2960
Most usages of the embedded ZK will not be in an ensemble (which
requires at least three servers). That bug does not affect ZK servers
running standalone. When running in a multi-server ensemble, 3.4.11
swaps the settings for dataDir and dataLogDir.
Thanks,
