Arrow reader should reject unsigned Parquet integers #14547
Description
Apache Iceberg version
main (development)
Query engine
None
Please describe the bug 🐞
The current implementation of Arrow reader within Iceberg will read each integer field as a signed integer, without considering the flag on the logical type annotation which mark that the integer should be interpreted as signed or unsigned value. Since Iceberg doesn't have unsigned integer type, I think the code should throw an exception, if the Parquet logical type is an unsigned integer.
