THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

The type and level of contributions considered may vary by project area -- for example, we greatly encourage contributors who want to work on mainly the documentation, or mainly on platform support for specific OSes, storage systems, etc.
Review Process
All contributions should be reviewed before merging as described in Contributing to Spark. In particular, if you are working on an area of the codebase you are unfamiliar with, look at the Git history for that code to see who reviewed patches before. You can do this using git log --format=full <filename>, by examining the "Commit" field to see who committed each patch.
How to Merge a Pull Request
Changes pushed to the master branch on Apache cannot be removed; that is, we can't force-push to it. So please don't add any test commits or anything like that, only real patches.
