> PySpark Bindings for K8S - make Python 3 the default
> ----------------------------------------------------
>
> Key: SPARK-24516
> URL: https://issues.apache.org/jira/browse/SPARK-24516
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes, PySpark
> Affects Versions: 2.4.0
> Reporter: Ondrej Kokes
> Priority: Minor
>
> Initial PySpark-k8s bindings have just been resolved (SPARK-23984), but the
> default Python version there is 2. While you can override this by setting it
> to 3, I think we should have sensible defaults.
> Python 3 has been around for ten years and is the clear successor, Python 2
> has only 18 months left in terms of support. There isn't a good reason to
> suggest Python 2 should be used, not in 2018 and not when both versions are
> supported.
