Hi Shawn, Help me understand this. Are you saying this is https://wiki.apache.org/solr/SolrConfigXml#System_property_substitution how we should specify the "dataDir"?
In that link, there is the statement "substituted can be put into a properties file" but it is not clear what this "properties file" is. Is it "solrcore.properties"? If so, where is that file and where should it be (assuming I must create it). Also, I looked at https://cwiki.apache.org/confluence/display/solr/Format+of+solr.xml and I cannot find an example of "dataDir". I also found this: https://wiki.apache.org/solr/Solr.xml%204.4%20and%20beyond but this link, while it talks about "dataDir" it does not show an example of how to specify it in solr.xml file. In my case, I'm on 5.2.1 a none cloud setup (just 1 core). I.e.: my setup is very similar to "\solr-5.2.1\example\example-DIH\solr".
