Release process.

Create a Release Tag from the release branch

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

Create a tarball

Note that running the rat tool can create some artifacts that we do not want in the tarball.
Make sure that you are tarring up a fresh checkout of the release branch.

 cp -R ambari-svn-x.y.z ambari-x.y.z-incubating
 tar --exclude=.svn -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

Upload the artifacts to your apache home:

The artifacts then need to be copied over to public_html/ambari-release-name-rc_i_/
