- In JIRA, "release" the version, setting the date to the end-of-vote date. Visit the "Administer Project" page, then the "Manage versions" page. You need to have the "Admin" role in HADOOP, HDFS, MAPREDUCE, and YARN.
- Set environment variable version for later steps.
export version=X.Y.Z Tag the release. Do it from the release branch and push the created tag to the remote repository:
No Format git tag -s rel/release-${version} -m "Hadoop ${version} release" git push origin rel/release-${version}- Copy release files to the distribution directory
Check out the corresponding svn repo if need be
No Format svn co https://dist.apache.org/repos/dist/release/hadoop/common/ hadoop-dist
- Copy the release files to hadoop-dist/hadoop-${version}
- Update the symlinks to current2 and stable2. The release directory usually contains just two releases, the most recent from two branches.
Commit the changes (it requires a PMC privilege)
No Format svn ci -m "Publishing the bits for release ${version}"- Usually binary tarball becomes larger than 300MB, so it cannot be directly uploaded to the distribution directory. Use the dev directory (https://dist.apache.org/repos/dist/dev/hadoop/) first and then move it to the distribution directory by
svn move.
- Update upstream branches to make them aware of this new release:
Copy and commit the CHANGELOG.md and RELEASENOTES.md:
No Format cp target/artifacts/RELEASENOTES.md hadoop-common-project/hadoop-common/src/site/markdown/release/${version}/RELEASENOTES.${version}.md cp target/artifacts/CHANGELOG.md hadoop-common-project/hadoop-common/src/site/markdown/release/${version}/CHANGELOG.${version}.mdCopy the jdiff xml files for this version to their appropriate directory.
No Format cp hadoop-common-project/hadoop-common/target/site/jdiff/xml/Apache_Hadoop_Common_${version}.xml hadoop-common-project/hadoop-common/dev-support/jdiff cp hadoop-hdfs-project/hadoop-hdfs/target/site/jdiff/xml/Apache_Hadoop_HDFS_${version}.xml hadoop-hdfs-project/hadoop-hdfs/dev-support/jdiff find hadoop-yarn-project -name "Apache_Hadoop_YARN_*_${version}.xml" | xargs -I{} cp {} hadoop-yarn-project/hadoop-yarn/dev-support/jdiff find hadoop-mapreduce-project -name "Apache_Hadoop_MapReduce_*_${version}.xml" | xargs -I{} cp {} hadoop-mapreduce-project/dev-support/jdiffUpdate

It contains TODO bug fixes, improvements and enhancements since TODO. Users are encouraged to read the [overview of major changes][1] since TODO. For details of TODO bug fixes, improvements, and other enhancements since the previous TODO release, please check [release notes][2] and [changelog][3]. [1]: /docs/r${VERSION}/index.html [2]: http://hadoop.apache.org/docs/r${VERSION}/hadoop-project-dist/hadoop-common/release/${VERSION}/RELEASENOTES.${VERSION}.html [3]: http://hadoop.apache.org/docs/r${VERSION}/hadoop-project-dist/hadoop-common/release/${VERSION}/CHANGELOG.${VERSION}.html EOF- Note: update all the TODO + the date. Don't use date from the future, it won't be rendered.
- Remove the
linked: trueline from the previous release file, eg. from src/release/3.0.0.md. Docs/downloads of the releases withlinked:truewill be linked from the menu. add the docs and update the
content/docs/currentlink, by doing the following:No Format cd content/docs tar xvf /path/to/hadoop-${version}-site.tar.gz # Update current2, current, stable and stable2 as needed. # For example rm current2 current ln -s r${version} current2 ln -s current2 current- Similarly update the symlinks for stable if need be.
- Check the rendering of the new site:
hugo serve && firefox http://localhost:1313 Regenerate the site, review it, then commit it per the instructions in HowToCommit. (The generated HTML files also should be committed. Both src and the rendered site are in the same repo.)
No Format hugo git add . git commit git push
- Send announcements to the user and developer lists once the site changes are visible. Optionally on Hadoop-PMC owned twitter account @hadoop. (For password reach out to private@)
- In JIRA, close issues resolved in the release. Disable mail notifications for this bulk change. Recommend not closing, since it prevents JIRAs from being edited and makes it more difficult to track backports.
- Add the release in "Apache Committee Report Helper" for the next board report to pick that up automatically at https://reporter.apache.org/addrelease.html?hadoop (Requires PMC member rights)
