Do I need to do something extra to work with DataImportHandler?

I'm trying to get the DataImportHandler to work. I start dse using:

./bin/dse -v
3.0

./bin/dse cassandra -s

I upload solrconfig.xml, schema.xml, and data-config.xml. The relevant part in solrconfig.xml seems to be:

<requestHandler name="/dataimport"
      class="org.apache.solr.handler.dataimport.DataImportHandler">
    <lst name="defaults">
      <str name="config">data-config.xml</str>
    </lst>
  </requestHandler>

When then trying to start the core via:

curl "http://localhost:8983/solr/admin/cores?action=CREATE&name=test.search"

I receive the following 500 response:

I included these jars in dse/resources/solr/lib :

apache-solr-dataimporthandler-extras-4.0.0.jar
apache-solr-dataimporthandler-4.0.0.jar

Now I'm getting a different error:

Should I be using 4.0.1 version? (that's what version number is attached to the solr jars already in that folder). If so, where do I get 4.0.1? Only 4.0.0 and 4.1.0 are available, and they don't make the issue go away.

For what it's worth, the jars from here:

http://mvn.riptano.com/content/repositories/snapshots/org/apache/solr/

result in the same error (tried 4.0.1-SNAPSHOT-6 versions of dataimporthandler jar)

Sorry for the delayed response. As you can see, there are issues using the Data Import Handler with DSE, even if you do go to the effort of manually copying the DIH jars from the stock Solr release.

We are currently investigating the issue and seeking a resolution. We will certainly let you know as soon as we come up with a short-term workaround.

But, for the moment, the Solr Data Import Handler is not currently supported in DSE.

Thank you for your patience.

Ok, thanks. I'll be looking forward to an update on this in the future.

Cheers!
