Ruifeng Zheng updated SPARK-54936:
----------------------------------
Description:
PySpark suffers a lot from behaviour changes in upstreams, like Pandas,
PyArrow, Numpy.
We should add tests to monitor the behaviour of key functions/features, like:
* 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) *
* time zone handling in pyarrow, pandas
* zero copy in pandas<->pyarrow data conversions *
* etc
Items with * are more important in pyspark
The new tests should be dedicated for upstream, spark stuffs should not be
involved.
The test data should consider:
1, Missing values, like Nullable data, NaN, pd.Nat, etc;
2, Empty instance (e.g. empty list);
3, invalid values to check the support and error;
4, Python instance (list,tuple,array,etc);
5, Pandas instance
6, Numpy instance
