Preparing for release
Setup for first time release managers
If you are being a release manager for the first time, you will need to run the following additional steps so that you are not blocked during the actual release process.
...
Create a Release Tag from the release branch
Code Block |
---|
svn copy https://svn.apache.org/repos/asf/incubator/ambari/branches/branch-x.y https://svn.apache.org/repos/asf/incubator/ambari/tags/release-x.y.z-rc0 -m "Ambari x.y.z Release Candidate"
|
Make sure it passes the apache rat tool.
mvn clean apache-rat:check
Sign the tarball
Configure SSH/SFTP to home.apache.org
SFTP to home.apache.org supports only Key-Based SSH Logins
Code Block | ||
---|---|---|
| ||
# Generate RSA Keys
mkdir ~/.ssh
chmod 700 ~/.ssh
ssh-keygen -t rsa -b 4096
# Note: This will create ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub files will be generated
# Upload Public RSA Key
Login at http://id.apache.org
Add Public SSH Key to your profile from ~/.ssh/id_rsa.pub
SSH Key (authorized_keys line):
Submit changes
# Verify SSH to minotaur.apache.org works
ssh -i ~/.ssh/id_rsa {username}@minotaur.apache.org
# SFTP to home.apache.org
sftp {username}@home.apache.org
mkdir public_html
cd public_html
put test #This test file is a sample empty file present in current working directory from which you sftp.
Verify URL http://home.apache.org/{username}/test |
Generate OpenGPG Key
You should get a signing key, keep it in a safe place, upload the public key to apache, and build a web of trust.
Code Block | ||
---|---|---|
| ||
gpg2 --gen-key
gpg2 --keyserver pgp.mit.edu --send-key {key}
gpg2 --armor --export {username}@apache.org > {username}.asc
Copy over {username}.asc to {username}@home.apache.org:public_html/~{username}.asc
Verify URL http://home.apache.org/~{username}/{username}.asc
Query PGP KeyServer http://pgp.mit.edu:11371/pks/lookup?search=0x{key}&op=vindex
Web of Trust:
Request others to sign your PGP key.
Login at http://id.apache.org
Add OpenPGP Fingerprint to your profile
OpenPGP Public Key Primary Fingerprint: XXXX YYYY ZZZZ ....
Submit changes
Verify that the public PGP key is exported to http://home.apache.org/keys/committer/{username}.asc |
Email dev@ambari.apache.org mailing list notifying that you will be creating the release branch at least one week in advance

Subject: Preparing Ambari X.Y.Z branch
Hi developers and PMCs,
I am proposing cutting a new branch branch-X.Y for Ambari X.Y.Z on __________ as per the outlined tasks in the Ambari Feature + Roadmap page (https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=30755705).
After making the branch, we (i.e., development community) should only accept blocker or critical bug fixes into the branch and harden it until it meets a high enough quality bar.
If you have a bug fix, it should first be committed to trunk, and after ensuring that it does not break any tests (including smoke tests), then it should be integrated to the Ambari branch-X.Y
If you have any doubts whether a fix should be committed into branch-X.Y, please email me for input at ____________
Stay tuned for updates on the release process.
Thanks |
Create the release branch
Create a branch for a release using branch-X.Y (ex: branch-2.1) as the name of the branch.
Note: Going forward, we should be creating branch-{majorVersion}.{minorVersion), so that the same branch can be used for maintenance releases.
Checkout the release branch
Code Block | ||
---|---|---|
| ||
git checkout branch-X.Y |
Update Ambari REST API docs
Starting with Ambari's trunk
branch as of Ambari 2.8, the release manager should generate documentation from existing source code. The documentation should be checked back into the branch before performing the release.
Code Block | ||
---|---|---|
| ||
# Generate the following artifacts:
# - Configuration markdown at docs/configuration/index.md
# - swagger.json and index.html at docs/api/generated/
cd ambari-server/
mvn clean compile exec:java@configuration-markdown test -Drat.skip -Dcheckstyle.skip -DskipTests -Dgenerate.swagger.resources
# Review and Commit the changes to branch-X.Y
git commit |
Update release version
Once the branch has been created, the release version must be set and committed. The changes should be committed to the release branch.
Ambari 2.8+
Starting with Ambari 2.8, the build process relies on Maven 3.5+ which allows the use of the ${revision}
tag. This means that the release version can be defined once in the root pom.xml
and then inherited by all submodules. In order to build Ambari with a specific build number, there are two methods:
mvn -Drevision=2.8.0.0.0 ...
- Editing the root
pom.xml
to include the new build number<revision>2.8.0.0-SNAPSHOT</revision>
To be consistent with prior releases, the pom.xml
should be updated in order to contain the new version.
Code Block | ||||
---|---|---|---|---|
| ||||
# Update the revision property to the release version
mvn versions:set-property -Dproperty=revision -DnewVersion=2.8.0.0.0
# Remove .versionsBackup files
git clean -f -x
# Review and commit the changes to branch-X.Y
git commit |
Ambari 2.7 and Earlier Releases (Deprecated)
Older Ambari branches still required that you update every pom.xml
manually through the below process:
Code Block | ||||||
---|---|---|---|---|---|---|
| ||||||
# Update the release version
mvn versions:set -DnewVersion=2.2.0.0.0
pushd ambari-metrics
mvn versions:set -DnewVersion=2.2.0.0.0

$ grep -r --include "pom.xml" "2.1.0-SNAPSHOT" .
# Remove .versionsBackup files
git clean -f -x -d
# Review and commit the changes to branch-X.Y
git commit |
Update KEYS
If this is the first time you have taken release management responsibilities, make sure to update the KEYS file and commit the updated KEYS in both the ambari trunk branch and the release branch. Also in addition to updating the KEYS file in the tree, you also need to push the KEYS file to https://dist.apache.org/repos/dist/release/ambari/
Code Block | ||||
---|---|---|---|---|
| ||||
gpg2 --list-keys jluniya@apache.org >> KEYS
gpg2 --armor --export jluniya@apache.org >> KEYS
# commit the changes to both trunk and new release branch
git commit
# push the updated KEYS file to https://dist.apache.org/repos/dist/release/ambari/.
# Only PMCs members can do this 'svn' step.
svn co https://dist.apache.org/repos/dist/release/ambari ambari_svn
cp {path_to_keys_file}/KEYS ambari_svn/KEYS
svn update KEYS
svn commit -m "Updating KEYS for Ambari" |
Setup Build
Setup Jenkins Job for the new branch on http://builds.apache.org
Creating Release Candidate
Note: The first release candidate is rc0. The following documented process assumes rc0, but replace it with the appropriate rc number as required.
Checkout the release branch
Code Block | ||
---|---|---|
| ||
git checkout branch-X.Y
|
Create a Release Tag from the release branch
Code Block | ||
---|---|---|
| ||
git tag -a release-X.Y.Z-rc0 -m 'Ambari X.Y.Z RC0'
git push origin release-X.Y.Z-rc0
|
Create a tarball
Code Block | ||
---|---|---|
| ||
# create a clean copy of the source
cd ambari-git-X.Y.Z
git clean -f -x -d
cd ..
cp -R ambari-git-X.Y.Z apache-ambari-X.Y.Z-src
# create ambari-web/public by running the build instructions per https://cwiki.apache.org/confluence/display/AMBARI/Ambari+Development
# once ambari-web/public is created, copy it as ambari-web/public-static
cp -R ambari-git-X.Y.Z/ambari-web/public apache-ambari-X.Y.Z-src/ambari-web/public-static
# make sure apache rat tool runs successfully
cp -R apache-ambari-X.Y.Z-src apache-ambari-X.Y.Z-ratcheck
cd apache-ambari-X.Y.Z-ratcheck
mvn clean apache-rat:check
cd ..
# if rat check fails, file JIRAs and fix them before proceeding.
# tar it up, but exclude git artifacts
tar --exclude=.git --exclude=.gitignore --exclude=.gitattributes -zcvf apache-ambari-X.Y.Z-src.tar.gz apache-ambari-X.Y.Z-src |
Sign the tarball
Code Block | ||
---|---|---|

Generate SHA512 checksums:
Code Block | ||
---|---|---|
| ||
sha512sum apache-ambari-X.Y.Z-src.tar.gz > apache-ambari-X.Y.Z-src.tar.gz.sha512
|
or
Code Block | ||
---|---|---|
| ||
openssl sha512 apache-ambari-X.Y.Z-src.tar.gz > apache-ambari-{release_number}-incubatingX.Y.Z-src.tar.gz.mds sha512 |
Upload the artifacts to your apache home:
The artifacts then need to be copied over (SFTP) to
Code Block | ||

Publishing and Announcement
After the vote passes:
Copy the bits to distribution folder for Apache Ambari:
Verify your PGP key is provided to Apache. Apache verifies that distributions are correctly signed.
- Login to https://id.apache.org and verify the fingerprint of PGP key used to sign above is provided. (gpg --fingerprint)
- Upload your PGP public key only to /home/<user>/.pgpkey
Publish the release as below:
Code Block | ||||
