Merge pull request #565 from pwendell/dev-scripts. Closes #565.
SPARK-1066: Add developer scripts to repository.
These are some developer scripts I've been maintaining in a separate public repo. This patch adds them to the Spark repository so they can evolve here and are clearly accessible to all committers.
I may do some small additional clean-up in this PR, but wanted to put them here in case others want to review. There are a few types of scripts here:
1. A tool to merge pull requests.
2. A script for packaging releases.
3. A script for auditing release candidates.
