Before opening a pull request, review the Contributing to Spark guide. It lists steps that are required before creating a PR. In particular, consider:
- Is the change important and ready enough to ask the community to spend time reviewing?
- Have you searched for existing, related JIRAs and pull requests?
- Is this a new feature that can stand alone as a third party project ?
- Is the change being proposed clearly explained and motivated?
