Wenchen Fan updated SPARK-54936:
--------------------------------
Affects Version/s: 4.3.0
(was: 4.2.0)
> Monitor behaviour changes from upstream
> ----------------------------------------
>
> Key: SPARK-54936
> URL: https://issues.apache.org/jira/browse/SPARK-54936
> Project: Spark
> Issue Type: Umbrella
> Components: PySpark, Tests
> Affects Versions: 4.3.0
> Reporter: Ruifeng Zheng
> Priority: Major
>
> 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 *
> * pd.api.types.pandas_dtype *
> * 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 dataset (e.g. empty list/dict, 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 taken into account, like
> {code:java}
> pandas_options = {
> "date_as_object": True,
> "coerce_temporal_nanoseconds": True,
> } {code}
> used in pa.Array.to_pandas
>
> All datatypes 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.
