Historically, Hadoop developers create patches and attache them to JIRA, andthen the Yetus bot runs precommit against the patch in the JIRA.
The Github PR is more convenient for code review and less hassle for committers to merge a commit. I am proposing for the community to prefer Github PR over the traditional patch-in-jira. This doesn't mean we will reject the traditional way, but we can move gradually to the new way. Additionally, update the Hadoop "How to contribute" wiki, and advertise that Github PR is the preferred method. Thoughts?
