-------------------------------------------

             Summary: solrcore.properties is not reloaded when core is reloaded
                 Key: SOLR-5931
                 URL: https://issues.apache.org/jira/browse/SOLR-5931
             Project: Solr
          Issue Type: Bug
          Components: multicore
    Affects Versions: 4.7
            Reporter: Gunnlaugur Thor Briem
            Priority: Minor


When I change solrcore.properties for a core, and then reload the core, the previous values of the properties in that file are still in effect. If I *unload* the core and then add it back, in the “Core Admin” section of the admin UI, then the changes in solrcore.properties do take effect.

My specific test case is a DataImportHandler where {{db-data-config.xml}} uses a property to decide which DB host to talk to:

{code:xml}
<dataSource driver="org.postgresql.Driver" name="meta" url="jdbc:postgresql://${dbhost}/${solr.core.name}" .../>
{code}

When I change that {{dbhost}} property in {{solrcore.properties}} and reload the core, the next dataimport operation still connects to the previous DB host. Reloading the dataimport config does not help. I have to unload the core (or fully restart the whole Solr) for the properties change to take effect.
