Creating a core in stand-alone mode _also_ requires that the config files are findable, in this case on disk rather than on Zookeeper (sorry for the misdirection).
So you need to create a directory, usually under solr_home that has the conf directory in it. That is the "instanceDir" that is one of the core creation parameters. Yes, this is a little arcane....
