Ruifeng Zheng updated SPARK-54936:
----------------------------------
Description:
PySpark suffers a lot from behaviour changes in upstreams, like Pandas,
PyArrow, Numpy.
Add tests to monitor the behaviour of key functions/features, including:
* pa.array *
* pa.scalar *
* pa.Array.from_pandas *
* pa.Array.to_pandas *
* pa.Array.cast *
* pa.Table.from_pandas *
* pa.Table.from_batches
* pa.Table.from_arrays
* pa.Table.from_pydict
* pa.Table.to_pandas *
* pa.Table.cast *
* pa.RecordBatch.from_arrays
* pa.RecordBatch.from_struct_array
* pa.RecordBatch.from_pylist
* pd.Series(data=arrow_data) *
* pd.Series.astype *
* pd.api.types.is_xxx *
* time zone handling in pyarrow, pandas
* zero copy in pandas<->pyarrow data conversions *
* ...
Items with * are more important in pyspark
Following data should be taken into account:
1, Missing values, like Nullable data, NaN, pd.Nat, etc;
2, Empty instance (e.g. empty list, empty pa.Table/RecordBatch);
3, invalid values to check the support and error;
4, Python instance (list,tuple,array,etc);
5, Pandas instance
6, Numpy instance
Arguments used in PySpark should be tested, like
{code:java}
pandas_options = {
"date_as_object": True,
"coerce_temporal_nanoseconds": True,
} {code}
used in pa.Array.to_pandas
All datatype should be tested, including:
1, all Spark datatypes;
2, all PyArrow datatypes;
3, all Pandas datatypes, .e.g for floats, np.float64, pd.Float64Dtype(),
pd.ArrowDtype(pa.float64()) / double[pyarrow]
The new tests should be dedicated for upstream, spark session should not be
launched.
