ccat3z opened a new pull request, #8862:
URL: https://github.com/apache/incubator-gluten/pull/8862
## What changes were proposed in this pull request?
An ORC file written by an old version has no field names in the physical
schema. To read it, we must map table schema to file schema using indices. This
PR made the following changes.
1. Passthrough `ScanTransformer#getDataColumns` as table schema to Velox.
2. Enable k{Parquet,Orc}UseColumnNames and kOrcUseNestedColumnNames in Velox
to match spark default behavior, which always map table schema to physical file
schema using name.
