------------------------------------------
Summary: Incorrect annotations in
SeriesGroupBy._cleanup_and_return
Key: SPARK-37678
URL: https://issues.apache.org/jira/browse/SPARK-37678
Project: Spark
Issue Type: Bug
Components: PySpark
Affects Versions: 3.3.0
Reporter: Maciej Szymkiewicz
[{{SeriesGroupBy._cleanup_and_return}}|https://github.com/apache/spark/blob/02ee1ae10b938eaa1621c3e878d07c39b9887c2e/python/pyspark/pandas/groupby.py#L2997-L2998]
annotations
{code:python}
def _cleanup_and_return(self, pdf: pd.DataFrame) -> Series:
return first_series(pdf).rename().rename(self._psser.name)
{code}
are inconsistent:
- If {{pdf}} is {{pd.DataFrame}} then output should be {{pd.Series}}.
- If output is {{ps.Series}} then {{pdf}} should be {{ps.DataFrame}}.
Doesn't seem like the method is used (it is possible that my search skills and
PyCharm inspection failed), so I am not sure which of these options was
intended.
