If the configoverlay.json file is in the same zookeeper path as
solrconfig.xml, then you MIGHT be able to use confFiles like I described
before.  I have no idea whether it would actually work, though.  It's
entirely possible that SolrCloud cores will not transfer conf files to
slaves.  I've never tried it, I have no idea whether it's going to work or
not.

With SolrCloud, all configuration is in zookeeper.  If a conf directory
exists in a core directory, it is completely ignored.

I will go on record to say that if you're running SolrCloud, you should not
be using master/slave replication. SolrCloud *does* take over the
replication handler for its own purposes, and configures it dynamically
based on the needs of the moment.  I do not know what that would do to a
typical master/slave setup.  If you're going to do it anyway, you should
probably be using a handler with a name other than "/replication" for your
master-slave setup, because that's the handler name that SolrCloud will use.

Thanks,
