    Description

      The sorting order of the floating point values are not properly specified, therefore NaN values can cause skipping valid values when filtering. See PARQUET-1222 for more info.
      This issue is for ignoring statistics for float/double if it contains NaN to prevent data loss at the read path when filtering.
