+# 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:[email protected]).
+
+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 <[email protected]>
+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).
+
+###Â 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:
+
+```
+From: Release Manager
+To: [email protected]
+Subject: [VOTE] Apache CarbonData Release x.x.x
