Dear
I think that the issue is related to how knowage is configured.
I can see in the logs:
Caused by: java.lang.RuntimeException: it.eng.spagobi.utilities.database.DataBaseException: The database Apache Hive v2 cannot be used as cache
To use file data set you have to configure properly the cache (
https://knowage-suite.readthedocs.io/en/7.2/installation-guide/manual-installation.html#configuration-of-the-metadata-db-dialect )
1) create an empty schema
2) create a JNDI connection pool in server.xml
3) create a new Data Source inside Knowage, you have to mark as "Use as cache" this connection.
Remember to user Oracle, MySQL , Maria DB, PostGreSQL as cache DBMS.
Best Regards
Angelo
