@uros-b Update: the Hive serde nested nanos limitation I mentioned earlier is now fixed in 80583a20dea. Root cause: `HiveInspectors.unwrapperFor(ObjectInspector)` had no Catalyst type context, so nanos timestamps nested inside `struct`/`array`/`map` were deserialized as micros `Long` instead of `TimestampNanosVal` (the nanos special-casing only covered top-level columns), causing a `ClassCastException`. Fix: added a data-type-aware `unwrapperFor(ObjectInspector, DataType)` that produces `TimestampNanosVal` for nanos timestamp types and recurses through array/map/struct, used from `OrcFileFormat` for nested fields containing a nanos timestamp. The Hive nested/complex test is restored and expanded to cover `struct`/`array`/`map` across precisions 7/8/9. -- This is an automated message from the Apache Git Service.
