[jira] [Created] (SPARK-34544) pyspark toPandas() should return pd.DataFrame

Rafal Wojdyla created SPARK-34544:
-------------------------------------

             Summary: 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: 3.0.1
            Reporter: Rafal Wojdyla


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.
