> Mapping the `mode` argument to pandas
> -------------------------------------
>
> Key: SPARK-35806
> URL: https://issues.apache.org/jira/browse/SPARK-35806
> Project: Spark
> Issue Type: Sub-task
> Components: PySpark
> Affects Versions: 3.2.0
> Reporter: Haejoon Lee
> Priority: Major
>
> pandas on Spark has a argument named `mode` in the APIs below:
> * [DataFrame.to_csv|https://koalas.readthedocs.io/en/latest/reference/api/databricks.koalas.DataFrame.to_csv.html]
> * [DataFrame.to_json|https://koalas.readthedocs.io/en/latest/reference/api/databricks.koalas.DataFrame.to_json.html]
> * [DataFrame.to_table|https://koalas.readthedocs.io/en/latest/reference/api/databricks.koalas.DataFrame.to_table.html]
> * [DataFrame.to_delta|https://koalas.readthedocs.io/en/latest/reference/api/databricks.koalas.DataFrame.to_delta.html]
> * [DataFrame.to_parquet|https://koalas.readthedocs.io/en/latest/reference/api/databricks.koalas.DataFrame.to_parquet.html]
> * [DataFrame.to_orc|https://koalas.readthedocs.io/en/latest/reference/api/databricks.koalas.DataFrame.to_orc.html]
> * [DataFrame.to_spark_io|https://koalas.readthedocs.io/en/latest/reference/api/databricks.koalas.DataFrame.to_spark_io.html]
> And pandas has same argument, but the acceptable strings are different.
> So, we should map the acceptable string to pandas.
> e.g. mode=w will work as Spark's overwrite. In addition, mode can take Spark's overwrite too.
