Apache Hadoop Git/Jira FixVersion validation

Git commits in Apache Hadoop contains Jira number of the format HADOOP-XXXX or HDFS-XXXX or YARN-XXXX or MAPREDUCE-XXXX. While creating a release candidate, we also include changelist and this changelist can be identified based on Fixed/Closed Jiras with the correct fix versions. However, sometimes we face few inconsistencies between fixed Jira and Git commit message.

git_jira_fix_version_check.py script takes care of identifying all git commits with commit messages with any of these issues:

  1. commit is reverted as per commit message
  2. commit does not contain Jira number format in message
  3. Jira does not have expected fixVersion
  4. Jira has expected fixVersion, but it is not yet resolved

Moreover, this script also finds any resolved Jira with expected fixVersion but without any corresponding commit present.

This should be useful as part of RC preparation.

git_jira_fix_version_check supports python3 and it required installation of jira:

$ python3 --version
Python 3.9.7

$ python3 -m venv ./venv

$ ./venv/bin/pip install -r dev-support/git-jira-validation/requirements.txt

$ ./venv/bin/python dev-support/git-jira-validation/git_jira_fix_version_check.py

The script also requires below inputs:

1. First commit hash to start excluding commits from history:
   Usually we can provide latest commit hash from last tagged release
   so that the script will only loop through all commits in git commit
   history before this commit hash. e.g for 3.3.2 release, we can provide
   git hash: fa4915fdbbbec434ab41786cb17b82938a613f16
   because this commit bumps up hadoop pom versions to 3.3.2:
   https://github.com/apache/hadoop/commit/fa4915fdbbbec434ab41786cb17b82938a613f16

2. Fix Version:
   Exact fixVersion that we would like to compare all Jira's fixVersions
   with. e.g for 3.3.2 release, it should be 3.3.2.

3. JIRA Project Name:
   The exact name of Project as case-sensitive e.g HADOOP / OZONE

4. Path of project's working dir with release branch checked-in:
   Path of project from where we want to compare git hashes from. Local fork
   of the project should be up-to date with upstream and expected release
   branch should be checked-in.

5. Jira server url (default url: https://issues.apache.org/jira):
   Default value of server points to ASF Jiras but this script can be
   used outside of ASF Jira too.

Example of script execution:

JIRA Project Name (e.g HADOOP / OZONE etc): HADOOP
First commit hash to start excluding commits from history: fa4915fdbbbec434ab41786cb17b82938a613f16
Fix Version: 3.3.2
Jira server url (default: https://issues.apache.org/jira):
Path of project's working dir with release branch checked-in: /Users/vjasani/Documents/src/hadoop-3.3/hadoop

Check git status output and verify expected branch

On branch branch-3.3.2
Your branch is up to date with 'origin/branch-3.3.2'.
