Wanted to bring up 2 things about managing PRs: 1. Squash all commits before merging PRs to master
2. Include the jira in the final commit before merging to master Most projects (TLP and Incubator) do it - Mahout, Flink, Pirk, PredictionIO. For reference, see https://mahout.apache.org/developers/github.html for how its being done on Mahout.
