alamb opened a new issue, #10926:
URL: https://github.com/apache/datafusion/issues/10926
### Describe the bug
I noticed this while working on
https://github.com/apache/datafusion/pull/10852 with @marvinlanhenke
Basially, when generating statistics for a non existent column, the
StatisticsExtractor will return a null array of the type of the column not a
UInt64Array
Specifically
https://github.com/apache/datafusion/blob/2f4347647172f6997448b2e24d322b50c856f3a0/datafusion/core/src/datasource/physical_plan/parquet/statistics.rs#L871-L886
The same problem exists for `data_page_null_counts` and
`data_page_row_counts` (not for `row_group_row_counts`
### To Reproduce
Try to call row_group_null_counts for a column that isn't in the parquet file
### Expected behavior
1. row_group_null_counts should always return an `UInt64Array` (not an
`ArrayRef`)
2. If there is not a column, the UInt64Array should be all nulls
