Hello,
Just wanted to update this thread. After continuing my troubleshooting, I found out the reason I was receiving Java class errors in my DWH logs. I was missing several plugins in the /opt/kalt/pentaho/pdi/plugins/steps/ directory, specifically in my case MappingFieldRunner/ MySQLInserter/ ShapeFileReader3/. After replacing these and running the DWH script from kaltura/bin/, I am not receiving any errors in the logs. I am now waiting to see if the KMC updates.
