For Bug Fix release: 

Here is how to go about a bug fix release.

• Create a branch in your repo (<user>/hudi). 
• cherry pick commits from master that needs to be part of this release. (git cherry-pick commit-hash)
• Ensure both compilation and tests are good. 
• I assume you will have apache/hudi as upstream. If not add it as upstream
• Once the branch is ready with all commits, go ahead and push your branch to upstream. 
• Go to apache/hudi repo locally and pull this branch. Here after you can work on this branch and push to origin when need be. 
• Do not forget to set the env variables from above section.
