    +# Apache CarbonData Release Guide
    +
    +Apache CarbonData periodically declares and publishes releases.
    +
    +Each release is executed by a _Release Manager_, who is selected among the CarbonData
committers.
    + This document describes the process that the Release Manager follows to perform a release.
Any 
    + changes to this process should be discussed and adopted on the 
    + [dev@ mailing list](mailto:dev@carbondata.incubator.apache.org).
    + 
    +Please remember that publishing software has legal consequences. This guide complements
the 
    +foundation-wide [Product Release Policy](http://www.apache.org/dev/release.html) and
[Release 
    +Distribution Policy](http://www.apache.org/dev/release-distribution).
    +
    +## Decide to release
    +
    +Deciding to release and selecting a Release Manager is the first step of the release
process. 
    +This is a consensus-based decision of the entire community.
    +
    +Anybody can propose a release on the dev@ mailing list, giving a solid argument and nominating
a 
    +committer as the Release Manager (including themselves). There's no formal process, no
vote 
    +requirements, and no timing requirements. Any objections should be resolved by consensus
before 
    +starting the release.
    +
    +_Checklist to proceed to next step:_
    +
    +1. Community agrees to release
    +2. Community selects a Release Manager
    +
    +## Prepare for the release
    +
    +Before your first release, you should perform one-time configuration steps. This will
set up your
    + security keys for signing the artifacts and access release repository.
    + 
    +To prepare for each release, you should audit the project status in the Jira, and do
necessary 
    +bookkeeping. Finally, you should tag a release.
    +
    +### One-time setup instructions
    +
    +#### GPG Key
    +
    +You need to have a GPG key to sign the release artifacts. Please be aware of the ASF-wide

    +[release signing guidelines](https://www.apache.org/dev/release-signing.html). If you
don't have 
    +a GPG key associated with your Apache account, please create one according to the guidelines.
    +
    +Determine your Apache GPG key and key ID, as follows:
    +
    +```
    +gpg --list-keys
    +```
    +
    +This will list your GPG keys. One of these should reflect your Apache account, for exemple:
    +
    +```
    +pub   2048R/845E6689 2016-02-23
    +uid                  Nomen Nescio <anonymous@apache.org>
    +sub   2048R/BA4D50BE 2016-02-23
    +```
    +
    +Here, the key ID is the 8-digit hex string in the `pub` line: `845E6689`.
    +
    +Now, add your Apache GPG key to the CarbonData's `KEYS` file in `dev` and `release` repositories

    +at `dist.apache.org`. Follow the instructions listed at the top of these files.
    + 
    +Configure `git` to use this key when signing code by giving it your key ID, as follows:
    +
    +```
    +git config --global user.signingkey 845E6689
    +```
    +
    +You may drop the `--global` option if you'd prefer to use this key for the current repository
only.
    +
    +You may wish to start `gpg-agent` to unlock your GPG key only once using your passphrase.

    +Otherwise, you may need to enter this passphrase several times. The setup of `gpg-agent`
varies 
    +based on operating system, but may be something like this:
    +
    +```
    +eval $(gpg-agent --daemon --no-grab --write-env-file $HOME/.gpg-agent-info)
    +export GPG_TTY=$(tty)
    +export GPG_AGENT_INFO
    +```
    +
    +#### Access to Apache Nexus
    +
    +Configure access to the [Apache Nexus repository](https://repository.apache.org), used
for 
    +staging repository and promote the artifacts to Maven Central.
    +
    +1. You log in with your Apache account.
    +2. Confirm you have appropriate access by finding `org.apache.carbondata` under `Staging
Profiles`.
    +3. Navigate to your `Profile` (top right dropdown menu of the page).
    +4. Choose `User Token` from the dropdown, then click `Access User Token`. Copy a snippet
of the 
    +Maven XML configuration block.
    +5. Insert this snippet twice into your global Maven `settings.xml` file, typically `${HOME]/
    +.m2/settings.xml`. The end result should look like this, where `TOKEN_NAME` and `TOKEN_PASSWORD`

    +are your secret tokens:
    +
    +```
    + <settings>
    +   <servers>
    +     <server>
    +       <id>apache.releases.https</id>
    +       <username>TOKEN_NAME</username>
    +       <password>TOKEN_PASSWORD</password>
    +     </server>
    +     <server>
    +       <id>apache.snapshots.https</id>
    +       <username>TOKEN_NAME</username>
    +       <password>TOKEN_PASSWORD</password>
    +     </server>
    +   </servers>
    + </settings>
    +```
    +
    +#### Create a new version in Jira
    +
    +When contributors resolve an issue in Jira, they are tagging it with a release that will
contain 
    +their changes. With the release currently underway, new issues should be resolved against
a 
    +subsequent future release. Therefore, you should create a release item for this subsequent

    +release, as follows:
    +
    +1. In Jira, navigate to `CarbonData > Administration > Versions`.
    +2. Add a new release: choose the next minor version number compared to the one currently

    +underway, select today's date as the `Start Date`, and choose `Add`. 
    +
    +#### Triage release-blocking issues in Jira
    +
    +There could be outstanding release-blocking issues, which should be triaged before proceeding
to 
    +build the release. We track them by assigning a specific `Fix Version` field even before
the 
    +issue is resolved.
    +
    +The list of release-blocking issues is available at the [version status page](https://issues.apache.org/jira/browse/CARBONDATA/?selectedTab=com.atlassian.jira.jira-projects-plugin:versions-panel).

    +Triage each unresolved issue with one of the following resolutions:
    +
    +* If the issue has been resolved and Jira was not updated, resolve it accordingly.
    +* If the issue has not been resolved and it is acceptable to defer until the next release,
update
    + the `Fix Version` field to the new version you just created. Please consider discussing
this 
    + with stakeholders and the dev@ mailing list, as appropriate.
    +* If the issue has not been resolved and it is not acceptable to release until it is
fixed, the 
    + release cannot proceed. Instead, work with the CarbonData community to resolve the issue.
    + 
    +#### Review Release Notes in Jira
    +
    +Jira automatically generates Release Notes based on the `Fix Version` applied to the
issues. 
    +Release Notes are intended for CarbonData users (not CarbonData committers/contributors).
You 
    +should ensure that Release Notes are informative and useful.
    +
    +Open the release notes from the [version status page](https://issues.apache.org/jira/browse/CARBONDATA/?selectedTab=com.atlassian.jira.jira-projects-plugin:versions-panel)
    +by choosing the release underway and clicking Release Notes.
    +
    +You should verify that the issues listed automatically by Jira are appropriate to appear
in the 
    +Release Notes. Specifically, issues should:
    +
    +* Be appropriate classified as `Bug`, `New Feature`, `Improvement`, etc.
    +* Represent noteworthy user-facing changes, such as new functionality, backward-incompatible

    +changes, or performance improvements.
    +* Have occurred since the previous release; an issue that was introduced and fixed between

    +releases should not appear in the Release Notes.
    +* Have an issue title that makes sense when read on its own.
    +
    +Adjust any of the above properties to the improve clarity and presentation of the Release
Notes.
    +
    +#### Verify that a Release Build works
    +
    +Run `mvn clean install -Prelease` to ensure that the build processes that are specific
to that 
    +profile are in good shape.
    +
    +_Checklist to proceed to the next step:_
    +
    +1. Release Manager's GPG key is published to `dist.apache.org`.
    +2. Release Manager's GPG key is configured in `git` configuration.
    +3. Release Manager has `org.apache.carbondata` listed under `Staging Profiles` in Nexus.
    +4. Release Manager's Nexus User Token is configured in `settings.xml`.
    +5. Jira release item for the subsequent release has been created.
    +6. There are no release blocking Jira issues.
    +7. Release Notes in Jira have been audited and adjusted.
    +
    +### Build a release
    +
    +Use Maven release plugin to tag and build release artifacts, as follows:
    +
    +```
    +mvn release:prepare
    +```
    +
    +Use Maven release plugin to stage these artifacts on the Apache Nexus repository, as
follows:
    +
    +```
    +mvn release:perform
    +```
    +
    +Review all staged artifacts. They should contain all relevant parts for each module,
including 
    +`pom.xml`, jar, test jar, source, etc. Artifact names should follow 
    +[the existing format](https://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.apache.carbondata%22)
    +in which artifact name mirrors directory structure. Carefully review any new artifacts.
    +
    +Close the staging repository on Nexus. When prompted for a description, enter "Apache
CarbonData 
    +x.x.x release".
    +
    +### Stage source release on dist.apache.org
    +
    +Copy the source release to dev repository on `dist.apache.org`.
    +
    +1. If you have not already, check out the Incubator section of the `dev` repository on
`dist
    +.apache.org` via Subversion. In a fresh directory:
    +
    +```
    +svn co https://dist.apache.org/repos/dist/dev/incubator/carbondata
    +```
    +
    +2. Make a directory for the new release:
    +
    +```
    +mkdir x.x.x
    +```
    +
    +3. Copy the CarbonData source distribution, hash, and GPG signature:
    +
    +```
    +cp apache-carbondata-x.x.x-source-release.zip x.x.x
    +```
    +
    +4. Add and commit the files:
    +
    +```
    +svn add x.x.x
    +svn commit
    +```
    +
    +5. Verify the files are [present](https://dist.apache.org/repos/dist/dev/incubator/carbondata).
    +
    +### Propose a pull request for website updates
    +
    +The final step of building a release candidate is to propose a website pull request.
    +
    +This pull request should update the following page with the new release:
    +
    +* `src/main/webapp/index.html`
    +* `src/main/webapp/docs/latest/mainpage.html`
    +
    +_Checklist to proceed to the next step:_
    +
    +1. Maven artifacts deployed to the staging repository of 
    +[repository.apache.org](https://repository.apache.org)
    +2. Source distribution deployed to the dev repository of
    +[dist.apache.org](https://dist.apache.org/repos/dist/dev/incubator/carbondata/)
    +3. Website pull request to list the release.
    +
    +## Vote on the release candidate
    +
    +Once you have built and individually reviewed the release candidate, please share it
for the 
    +community-wide review. Please review foundation-wide [voting guidelines](http://www.apache.org/foundation/voting.html)
    +for more information.
    +
    +Start the review-and-vote thread on the dev@ mailing list. Here's an email template;
please 
    +adjust as you see fit:
    +
    +```
