A single commit message consisting of:

1. Pull request title (which includes JIRA number and component, e.g. [SPARK-1234][MLlib])

2. Pull request description

3. List of authors contributing to the patch

The main thing that changes is 3: we used to also include the individual commits to the pull request branch that are squashed.

Just to clarify, the proposal is to have a single commit msg giving the jira and pr id?
That sounds like a good change to have.

I took a look at the commit messages in git log -- it looks like the individual commit messages are not that useful to include, but do make the commit messages more verbose. They are usually just a bunch of extremely concise descriptions of "bug fixes", "merges", etc:

    cb3f12d [xxx] add whitespace
    6d874a6 [xxx] support pyspark for yarn-client

    89b01f5 [yyy] Update the unit test to add more cases
    275d252 [yyy] Address the comments
    7cc146d [yyy] Address the comments
    2624723 [yyy] Fix rebase conflict
    45befaa [yyy] Update the unit test
    bbc1c9c [yyy] Fix checkpointing doesn't retain driver port issue

Anybody against removing those from the merge script so the log looks cleaner? If nobody feels strongly about this, we can just create a JIRA to remove them, and only keep the author names.
