Work Description: pvary opened a new pull request #2427:
URL: https://github.com/apache/hive/pull/2427
### What changes were proposed in this pull request?
- Introduce a new configuration property: `iceberg.hive.keep.stats`. If this
property is set then we keep the statistics at a new Iceberg commit. Otherwise
we invalidate the stats as we can not make sure that they are correct.
- Fix a NullPointerExeption in HiveIcebergMetaHook which happens when we are
storing stats.
- Adds a new unit tests, and enhances the check that the stat values are
accurate
Also contains HIVE-25276 as a base.
### Why are the changes needed?
When someone modifies the Iceberg table outside of Hive then we should make
sure that the stats are invalid
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Extra unit test
