Release process.

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

git checkout branch-x.y.z

Make sure it passes the apache rat tool.

mvn clean apache-rat:check

Create a Release Tag from the release branch

git tag -a release-x.y.z-rc0 -m 'Ambari x.y.z RC0'
git push --tags origin

Create a tarball

 cd ambari-git-x.y.z
 git clean -f -x -d
 cd ..
 cp -R ambari-git-x.y.z ambari-x.y.z-incubating
 tar --exclude=.git -zcvf ambari-x.y.z-incubating.tar.gz ambari-x.y.z-incubating

Sign the tarball 

gpg2  --armor --output ambari-{release_number}-incubating.tar.gz.asc --detach-sig ambari-{release_number}-incubating.tar.gz

Generate MD5 checksums:

md5sum ambari-X.Y.Z-incubating.tar.gz > ambari-X.Y.Z-incubating.tar.gz.md5
sha1sum ambari-X.Y.Z-incubating.tar.gz > ambari-X.Y.Z-incubating.tar.gz.sha

or

openssl md5 ambari-X.Y.Z-incubating.tar.gz > ambari-X.Y.Z-incubating.tar.gz.md5
openssl sha1 ambari-X.Y.Z-incubating.tar.gz > ambari-X.Y.Z-incubating.tar.gz.sha
