Solr Core Discovery mode defining extra properties

We are upgrading to solr 4.4 and would like to be able to use the new core.properties for the new core discovery.

Currently, we have a couple of properties defined in the solr.xml for most of the cores, and I am not able to create these same properties in the new core.properties file.

Here is a core as currently defined in solr.xml:

<core name="core1003" instanceDir="core1003">
  <property name="xmlDataDir" value="D:\Solrfiles\ImportFiles\core1003.xml" />
</core>

This is then used in DIH-XPathEntityProcessor.xml with <str name="xmlDataDir">${xmlDataDir}</str>.

How can I define core specific property variables like this? It doesn't necessarily have to be in core.properties, but that would make it a little easier to manage.

In your core instance directories that contain your core.properties file create a conf/ subdirectory and a solrcore.properties file in it. Define your core specific properties there and it will be picked up automatically.

Alternatively, you can add a value for "properties" to your core.properties file to point to any other file:

properties=/your/path/here.properties

I believe but have not confirmed that for this to work your cores must load on startup and must not be transient. Any non-standard properties you add to core.properties will be ignored because the CoreDescriptor copy constructor only persists the following properties from that file in memory: instanceDir, config, schema, name and dataDir (see CoreDescriptor:91 in the 4.4.0 source). I believe this is a bug?
