> For supporting vectored reads in parquet, DECIMAL_64 support in ORC has been 
> disabled in HiveIcebergInputFormat. This causes regressions in queries.
> [https://github.com/apache/hive/blob/master/iceberg/iceberg-handler/src/main/java/org/apache/iceberg/mr/hive/HiveIcebergInputFormat.java#L182]
> It will be good to restore DECIMAL_64 support in iceberg input format.
