[jira] [Created] (SPARK-37036) Add util function to raise advice warning for pandas API on Spark.

-----------------------------------

             Summary: Add util function to raise advice warning for pandas API on Spark.
                 Key: SPARK-37036
                 URL: https://issues.apache.org/jira/browse/SPARK-37036
             Project: Spark
          Issue Type: Improvement
          Components: PySpark
    Affects Versions: 3.2.0
            Reporter: Haejoon Lee


Pandas API on Spark has some features that potentially cause the performance degradation or an unexpected behavior e.g. `sort_index`, `index_col`, `to_pandas`, etc.

 

We should raise the proper advice warning for those functions so that users can adjust their pandas-on-Spark code base more robust.
