+1 on git, either on github or closer to the linux model with real
- I've been using it for just about all of my development and it works
pretty nicely. I push everything to github as I'm working. Then I
squash commits and create a diff to post on jira.
- I would suggest that since hbase's code base moves so rapidly, a
rebased branch should probably be a requirement before merging.
Otherwise the merge will get pretty interesting for very long lived
