HowToRelease
Before doing the preparation tasks in the above articles, we have to do the following tasks:
Create 3.4.0 and 3.3.1 versions in COMMON/HDFS/YARN/MAPREDUCE projects
Announce the process as the past RMs did. For example:
"We will cut branch-3.3 and branch-3.3.0 in this weekend."
"branch-3.3 is cut, please commit a change to branch-3.3 if you want to fix the issue in 3.3.x."
"branch-3.3.0 is cut, please do not commit a change to branch-3.3.0 unless it is a blocker/critical issue."
3.3.1 Blocker/Critical issues
