0001 ## Contributing to Spark
0003 *Before opening a pull request*, review the
0004 [Contributing to Spark guide](https://spark.apache.org/contributing.html).
0005 It lists steps that are required before creating a PR. In particular, consider:
0007 - Is the change important and ready enough to ask the community to spend time reviewing?
0008 - Have you searched for existing, related JIRAs and pull requests?
0009 - Is this a new feature that can stand alone as a [third party project](https://spark.apache.org/third-party-projects.html) ?
0010 - Is the change being proposed clearly explained and motivated?
0012 When you contribute code, you affirm that the contribution is your original work and that you
0013 license the work to the project under the project's open source license. Whether or not you
0014 state this explicitly, by submitting any copyrighted material via pull request, email, or
0015 other means you agree to license the material under the project's open source license and
0016 warrant that you have the legal authority to do so.
