@jongyoul This is for the zeppelin HA feature which will involve many PRs.
Here's the pros and cons of creating new branch.
Pros.
1. Move fast of implementing this feature
2. Keep the master branch stable.
3. Interested users can try this feature earlier.
4. This feature branch will become much stable before merging into master
branch.
Cons.
1. Merging into master will take a lot time.
That's why I think creating new branch for this feature is necessary.
