Taken a while to suss this, but the solr config file wasn't being copied to the image until after "solrctl init" had run, also zookeeper needs to be running when "solrctl init" is issued so needed "service hbase-master start".

Solr samples now install and run through hue

Hi Andy! Thank you for the collaboration! I'm tested now via Docker Hub and the Cloudera Search is fully working. Thanks! :D
