Resolution

If you encounter this error while using Hive's "standalone" jar file to support our Hive adapter, you will need to modify this jar file (ie; hive-jdbc-1.2.2-standalone.jar).
Open the jar file (using winzip will suffice) and remove the org\slf4j directory from the jar file's contents.
Save the resulting jar file and place that back into your TDV server's \conf\adapters\system\<your Hive adapter version>

Restart the server to reload the jar file.  The connection is now expected to succeed.
