[jira] [Created] (SPARK-34629) Python type hints improvement

Hyukjin Kwon created SPARK-34629:
------------------------------------

             Summary: Python type hints improvement
                 Key: SPARK-34629
                 URL: https://issues.apache.org/jira/browse/SPARK-34629
             Project: Spark
          Issue Type: Improvement
          Components: PySpark
    Affects Versions: 3.1.2
            Reporter: Hyukjin Kwon


We added PySpark type hints at SPARK-32681

However, looks like there are still many missing APIs to type. I maintain a project called [Koalas](https://github.com/databricks/koalas), and I found these errors https://gist.github.com/HyukjinKwon/9faabc5f2680b56007d71ef7cf0ad400

For example, {{pyspark.__version__}} and {{pyspark.sql.Column.contains}} are missing in the type hints.

This umbrella JIRA targets to identify such cases and improve Python type hints in PySpark.
