---------------------------------
Affects Version/s: (was: 3.0.1)
3.1.1
> pyspark toPandas() should return pd.DataFrame
> ---------------------------------------------
>
> Key: SPARK-34544
> URL: https://issues.apache.org/jira/browse/SPARK-34544
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 3.1.1
> Reporter: Rafal Wojdyla
> Assignee: Maciej Szymkiewicz
> Priority: Critical
>
> Right now {{toPandas()}} returns {{DataFrameLike}}, which is an incomplete "view" of pandas {{DataFrame}}. Which leads to cases like mypy reporting that certain pandas methods are not present in {{DataFrameLike}}, even tho those methods are valid methods on pandas {{DataFrame}}, which is the actual type of the object. This requires type ignore comments or asserts.
