Making A Release

The project follows GitFlow. Thus start the release using :

git flow release start <RELEASE-VERSION>

This will create a release branch and switch to that.

Bump up to the release version using :

mvn tycho-versions:set-version -DnewVersion=<RELEASE-VERSION>

Make a complete build :

mvn clean install

Make the required changes/bug fixes. Then commit all the changes back to release branch.

sign the release using :

mvn verify gpg:sign install:install deploy:deploy

Create MD5 and SHA1 checksums for the source distribution:

md5sum -b hdt-<RELEASE-VERSION>-hdt-assembly-src.tar.gz > hdt-<RELEASE-VERSION>-hdt-assembly-src.tar.gz.md5

md5sum -b hdt-<RELEASE-VERSION>-hdt-assembly-bin.tar.gz > hdt-<RELEASE-VERSION>-hdt-assembly-bin.tar.gz.md5

sha1sum -b hdt-<RELEASE-VERSION>-hdt-assembly-src.tar.gz > hdt-<RELEASE-VERSION>-hdt-assembly-src.tar.gz.sha1

sha1sum -b hdt-<RELEASE-VERSION>-hdt-assembly-bin.tar.gz > hdt-<RELEASE-VERSION>-hdt-assembly-bin.tar.gz.sha1

Copy Binary and Source Release Artifacts, signature and checksum from dist/target/ to people.apache.org:~/public_html/

Finish the release to merge back the changes to development and master :

git flow release finish <VERSION>

Now go back on development branch and bump up to the next development version using :

mvn tycho-versions:set-version -DnewVersion=<NEXT-VERSION>

Now make a complete build to check all changes :

mvn clean install

Then commit all the changes back to development

Run the Vote.

Send a "VOTE" to the developer mailing list including links to release artifacts. A VOTE always contains two parts. Send an email to the developer mailing list with the subject line:

[VOTE] Release HDT version x.xx.xx

After the vote is over, send a "RESULT" email to the list with the subject line:

[RESULT][VOTE] Release HDT version x.xx.xx

After the PPMC vote passes initiate a vote on the general mailing list

Votes on whether a package is ready to be released use majority approval -- i.e., at least three PPMC(for dev mailing list)/ IPMC(for general) members must vote affirmatively for release, and there must be more positive than negative votes.

Distribute and announce

If VOTE passes : Upload the release to https://dist.apache.org/repos/dist/release/incubator/hdt/

Send an announcement to the mailing list. Email announcements should have the subject line:

[ANNOUNCE] Released HDT version x.xx.xx


Apache Hadoop Development Tools is an effort undergoing incubation at The Apache Software Foundation(ASF) sponsored by the Apache Incubator PMC.Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
