bq. To be clear I deleted the actual index files out from under the running master
I'm assuming *nix here since Windows won't let you delete a file that has an open file handle... Did you then restart the master? Aside from any checks about refusing to replicate an empty index, just deleting the files without reloading the core (or restarting Solr) won't do it. Files disappear all the time out from under a running Solr, specifically during merges. However on linux machines those files are still available until the last file handle is closed, and Solr still points to those files until a hard commit or restart. More technically, until a new Searcher is opened. Here's a check: query the _master_ after deleting the index. Absent a commit of some sort, you'll probably get results. Mind you you still may not see a replication of an empty index, this is just another complication that you need to be aware of.
