[jira] [Updated] (SPARK-34629) Python type hints improvement
[ https://issues.apache.org/jira/browse/SPARK-34629?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hyukjin Kwon updated SPARK-34629:
---------------------------------
Description:
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.
I believe this is the same case to other projects that enables mypy in their project (presumably also given SPARK-34544).
This umbrella JIRA targets to identify such cases and improve Python type hints in PySpark.
