+Thanks for improving the project! *Before opening a pull request*, review the
+[Contributing to Spark guide](https://spark.apache.org/contributing.html).
+It lists steps that are required before creating a PR. In particular, consider:

reviewing?

project](https://spark.apache.org/third-party-projects.html) ?
+- Is the change being proposed clearly explained and motivated?
+
+When you contribute code, you affirm that the contribution is your original
work and that you
+license the work to the project under the project's open source license.

+state this explicitly, by submitting any copyrighted material via pull
request, email, or
+other means you agree to license the material under the project's open source
license and
+warrant that you have the legal authority to do so.
