Descripción
I just want to confirm that we respect the following Hive properties outlined in the documentation:
- Hive: http://orc.apache.org/docs/hive-config.html
My only concern is that our Orc dialect for Hive Source and Sink delegates to the same code base for our native Orc Source and Sink and hence ignoring these table properties?
If this is the case we should automatically pick up these options from the Hive Metastore when using HiveSource and HiveSink, and support them natively when using the OrcSink and OrcSource?

Línea de trabajo
Check the HiveSource and HiveSink implementations to see if they delegate to OrcSource and OrcSource. Review the ORC dialect code to verify if Hive table properties from the metastore are being read and applied. Look for configuration handling in the ORC module and compare with the Hive config documentation. Determine what changes are needed to respect these properties in both Hive and native ORC contexts.
