Change subject: IMPALA-6542: Fix inconsistent write path of Parquet min/max statistics ...................................................................... IMPALA-6542: Fix inconsistent write path of Parquet min/max statistics Quick fix of Parquet write path until the Parquet community agrees on the ordering of floating point numbers. This commit ignores NaNs during min/max statistics calculation. Only write NaN as 'min_value' and 'max_value' if all the values are NaNs in the column chunk. Added e2e tests as well.
