The Release notes for Solr 6.6.0 include the following Upgrade Note:
On the face of it, this looks like a problem, since even HDP 2.6 only include Zookeeper 3.4.6.
Does this 'dependency' mean that Solr will not work with Zookeeper 3.4.6 or is it just documenting the fact that the Solr embedded Zookeeper instance is now 3.4.10?
