Yes, that is the best way to go, but only available for zk >3.5, I have spun up
zookeeper and checked /zookeeper/config.
Any idea if querying the ZK client for information for zk >3.5 will be added in
the near future?
Should I raise a JIRA for it?

I think that Solr should query the ZK client for information about what
server hosts are active, rather than relying on the connection string,
unless that information cannot be obtained by the client.
That will be particularly important now that Solr contains ZK client
version 3.5.x. When paired with servers also running 3.5 or later, it
is capable of dynamic reconfiguration. It is entirely possible that the
active server list will be very different than the connection string.
According to the ZK team, the /zookeeper/config znode has this
information. I do not know if that is new in version 3.5 or if it also
exists in 3.4.
Thanks,
Shawn
