# Which issue does this PR close? Closes #2427 # Rationale for this change Auron Iceberg native scan can fall back when the Iceberg scan schema contains data types that are not supported by native scan conversion. Before this change, unsupported metadata columns already had a clear fallback reason, but unsupported data columns did not. This made it harder to diagnose why an Iceberg scan stayed on Spark execution. # What changes are included in this PR? Adds an Iceberg fallback reason for unsupported scan schema data types. Reports unsupported field names and Spark SQL types in the never-convert reason. Extends the existing unsupported decimal Iceberg scan test to check the fallback reason. # Are there any user-facing changes? No API changes. Users may see a clearer fallback reason when an Iceberg native scan is skipped because of unsupported data types. # How was this patch tested? UT. # Was this patch authored or co-authored using generative AI tooling? - [ ] Yes - [x] No -- This is an automated message from the Apache Git Service.
