+    <h2>Preparing Spark Releases</h2>
+
+<h3>Background</h3>
+
+<p>The release manager role in Spark means you are responsible for a few different things:</p>
+
+<ol>
+  <li>Preparing for release candidates:
+    <ol>
+      <li>cutting a release branch</li>
+      <li>informing the community of timing</li>
+      <li>working with component leads to clean up JIRA</li>
+      <li>making code changes in that branch with necessary version updates</li>
+    </ol>
+  </li>
+  <li>Running the voting process for a release:
+    <ol>
+      <li>creating release candidates using automated tooling</li>
+      <li>calling votes and triaging issues</li>
+    </ol>
+  </li>
+  <li>Finalizing and posting a release:
+    <ol>
+      <li>updating the Spark website</li>
+      <li>writing release notes</li>
+      <li>announcing the release</li>
+    </ol>
+  </li>
+</ol>
+
+<h2>Preparing Spark for Release</h2>
+
+<p>The main step towards preparing a release is to create a release branch. This is done via 
+standard Git branching mechanism and should be announced to the community once the branch is 
+created. It is also good to set up Jenkins jobs for the release branch once it is cut to 
+ensure tests are passing (consult Josh Rosen and Shane Knapp for help with this).</p>
+
+<p>Next, ensure that all Spark versions are correct in the code base on the release branch (see 
+<a href="https://github.com/apache/spark/commit/01d233e4aede65ffa39b9d2322196d4b64186526">this example commit</a>).
+You should grep through the codebase to find all instances of the version string. Some known 
+places to change are:</p>
+
+<ul>
+  <li><strong>SparkContext</strong>. Search for VERSION (only for branch 1.x)</li>
+  <li><strong>Maven build</strong>. Ensure that the version in all the <code>pom.xml</code> files is <code>&lt;SPARK-VERSION&gt;-SNAPSHOT</code> 
+(e.g. <code>1.1.1-SNAPSHOT</code>). This will be changed to <code>&lt;SPARK-VERSION&gt;</code> (e.g. 1.1.1) automatically by 
+Maven when cutting the release. Note that there are a few exceptions that should just use 
+<code>&lt;SPARK-VERSION&gt;</code>, like <code>extras/java8-tests/pom.xml</code>. These modules are not published as artifacts.</li>
+  <li><strong>Spark REPLs</strong>. Look for the Spark ASCII art in <code>SparkILoopInit.scala</code> for the Scala shell 
+and in <code>shell.py</code> for the Python REPL.</li>
+  <li><strong>Docs</strong>. Search for VERSION in <code>docs/_config.yml</code></li>
+</ul>
+
+<p>Finally, update <code>CHANGES.txt</code> with this script in the Spark repository. <code>CHANGES.txt</code> captures 
+all the patches that have made it into this release candidate since the last release.</p>
+
+<pre><code>$ export SPARK_HOME=&lt;your Spark home&gt;
+$ cd spark
+# Update release versions
+$ vim dev/create-release/generate-changelist.py
+$ dev/create-release/generate-changelist.py
+</code></pre>
+
+<p>This produces a <code>CHANGES.txt.new</code> that should be a superset of the existing <code>CHANGES.txt</code>. 
+Replace the old <code>CHANGES.txt</code> with the new one (see 
+<a href="https://github.com/apache/spark/commit/131c62672a39a6f71f6834e9aad54b587237f13c">this example commit</a>).</p>
+
+<h3>Cutting a Release Candidate</h3>
+
+<p>If this is not the first RC, then make sure that the JIRA issues that have been solved since the 
+last RC are marked as <code>FIXED</code> in this release version.</p>
+
+<ul>
+  <li>A possible protocol for this is to mark such issues as <code>FIXED</code> in next maintenance release. 
+For example if you are cutting RC for 1.0.2, mark such issues as <code>FIXED</code> in 1.0.3.</li>
+  <li>When cutting new RC, find all the issues that are marked as <code>FIXED</code> for next maintenance 
+release, and change them to the current release.</li>
+  <li>Verify from <code>git log</code> whether they are actually making it in the new RC or not.</li>
+</ul>
+
+<p>The process of cutting a release candidate has been automated via the AMPLab Jenkins. There are 
+Jenkins jobs that can tag a release candidate and create various packages based on that candidate. 
+The recommended process is to ask the previous release manager to walk you through the Jenkins jobs.</p>
+
+<h3>Call a Vote on the Release Candidate</h3>
+
+<p>The release voting takes place on the Apache Spark developers list (the PMC is voting). 
+Look at past voting threads to see how this proceeds. The email should follow 
+<a href="http://mail-archives.apache.org/mod_mbox/spark-dev/201407.mbox/%3cCABPQxss7Cf+YaUuxCk0jnusH4207hCP4dkWn3BWFSvdnD86HHQ@mail.gmail.com%3e">this format</a>.</p>
+
+<ul>
+  <li>Make a shortened link to the full list of JIRAs using <a href="http://s.apache.org/">http://s.apache.org/</a></li>
+  <li>If possible, attach a draft of the release notes with the email</li>
+  <li>Make sure the voting closing time is in UTC format. Use this script to generate it</li>
+  <li>Make sure the email is in text format and the links are correct</li>
+</ul>
+
+<p>Once the vote is done, you should also send out a summary email with the totals, with a subject 
+that looks something like <code>[RESULT] [VOTE]...</code>.</p>
+
+<h3>Finalize the Release</h3>
+
+<p><strong>Be Careful!</strong></p>
+
+<p><strong>THIS STEP IS IRREVERSIBLE so make sure you selected the correct staging repository. Once you 
+move the artifacts into the release folder, they cannot be removed.</strong></p>
+
+<p>After the vote passes, find the staging repository and click Release and confirm. To upload the 
+binaries, you have to first upload them to the dev directory in the Apache Distribution repo, 
+and then move the binaries from dev directory to release directory. This &#8220;moving&#8221; is the only
+ way you can add stuff to the actual release directory.</p>
+
+<pre><code># Checkout the Spark directory in Apache distribution SVN "dev" repo
+$ svn co https://dist.apache.org/repos/dist/dev/spark/
+  
+# Make directory for this RC in the above directory
+mkdir spark-1.1.1-rc2
+ 
+# Download the voted binaries and add them to the directory
+$ scp andrewor14@people.apache.org:~/public_html/spark-1.1.1-rc2/* spark-1.1.1-rc2
+ 
+# NOTE: Remove any binaries you don\u2019t want to publish
+# E.g. never push MapR and *without-hive artifacts to apache
+$ rm spark-1.1.1-rc2/*mapr*
+$ rm spark-1.1.1-rc2/*without-hive*
+$ svn add spark-1.1.1-rc2
+$ svn commit -m "Add spark-1.1.1-rc2" --username "andrewor14"
+  
+# Move the sub-directory in "dev" to the
+# corresponding directory in "release"
+$ export SVN_EDITOR=vim
+$ svn mv https://dist.apache.org/repos/dist/dev/spark/spark-1.1.1-rc2 https://dist.apache.org/repos/dist/release/spark/spark-1.1.1
+</code></pre>
+
+<p>Verify that the resources are present in <a href="http://www.apache.org/dist/spark/">http://www.apache.org/dist/spark/</a>.
+It may take a while for them to be visible. This will be mirrored throughout the Apache network. 
+There are a few remaining steps.</p>
+
+<h4>Remove Old Releases from Mirror Network</h4>
+
+<p>Spark always keeps two releases in the mirror network: the most recent release on the current and 
+previous branches. To delete older versions simply use svn rm. The <code>downloads.js</code> file in the 
+website <code>js/</code> directory must also be updated to reflect the changes. For instance, the two 
+releases should be 1.1.1 and 1.0.2, but not 1.1.1 and 1.1.0.</p>
+
+<pre><code>$ svn rm https://dist.apache.org/repos/dist/release/spark/spark-1.1.0
+</code></pre>
+
+<h4>Update the Spark Apache Repository</h4>
+
+<p>Check out the tagged commit for the release candidate that passed and apply the correct version tag.</p>
+
+<pre><code>$ git checkout v1.1.1-rc2 # the RC that passed
+$ git tag v1.1.1
+$ git push apache v1.1.1
+ 
+# Verify that the tag has been applied correctly
+# If so, remove the old tag
+$ git push apache :v1.1.1-rc2
+$ git tag -d v1.1.1-rc2
+</code></pre>
+
+<p>Next, update remaining version numbers in the release branch. If you are doing a patch release, 
+see the similar commit made after the previous release in that branch. For example, for branch 1.0, 
+see <a href="https://github.com/apache/spark/commit/2a5514f7dcb9765b60cb772b97038cbbd1b58983">this example commit</a>.</p>
+
+<p>In general, the rules are as follows:</p>
+
+<ul>
+  <li><code>grep</code> through the repository to find such occurrences</li>
+  <li>References to the version just released. Upgrade them to next release version. If it is not a 
+documentation related version (e.g. inside <code>spark/docs/</code> or inside <code>spark/python/epydoc.conf</code>), 
+add <code>-SNAPSHOT</code> to the end.</li>
+  <li>References to the next version. Ensure these already have <code>-SNAPSHOT</code>.</li>
+</ul>
+
+<!--
+<h4>Update the EC2 Scripts</h4>
+
+Upload the binary packages to the S3 bucket s3n://spark-related-packages (ask pwendell to do this). Then, change the init scripts in mesos/spark-ec2 repository to pull new binaries (see this example commit).
+For Spark 1.1+, update branch v4+
+For Spark 1.1, update branch v3+
+For Spark 1.0, update branch v3+
+For Spark 0.9, update branch v2+
+You can audit the ec2 set-up by launching a cluster and running this audit script. Make sure you create cluster with default instance type (m1.xlarge).
+-->
+
+<h4>Update the Spark Website</h4>
+
+<p>The website repository is located at 
+<a href="https://github.com/apache/spark-website">https://github.com/apache/spark-website</a>. 
+Ensure the docs were generated with the PRODUCTION=1 environment variable and with Java 7.</p>
+
+<pre><code># Build the latest docs
+$ git checkout v1.1.1
+$ cd docs
+$ JAVA_HOME=$JAVA_7_HOME PRODUCTION=1 jekyll build
+ 
+# Copy the new documentation to apache
+$ git clone https://github.com/apache/spark-website
+...
+$ cp -R _site spark-website/site/docs/1.1.1
+
+# Update the "latest" link
+$ cd spark/site/docs
+$ rm latest
+$ ln -s 1.1.1 latest
+</code></pre>
+
+<p>Next, update the rest of the Spark website. See how the previous releases are documented. 
+In particular, have a look at the changes to the <code>*.md</code> files in this commit (all the HTML 
+file changes are generated by <code>jekyll</code>).</p>
+
+<pre><code>$ git add 1.1.1
+$ git commit -m "Add docs for Spark 1.1.1" 
+</code></pre>
+
+<p>Then, create the release notes. The contributors list can be automatically generated through 
+<a href="https://github.com/apache/spark/blob/branch-1.1/dev/create-release/generate-contributors.py">this script</a>.
+It accepts the tag that corresponds to the current release and another tag that 
+corresponds to the previous (not including maintenance release). For instance, if you are 
+releasing Spark 1.2.0, set the current tag to v1.2.0-rc2 and the previous tag to v1.1.0.
+Once you have generated the initial contributors list, it is highly likely that there will be 
+warnings about author names not being properly translated. To fix this, run 
+<a href="https://github.com/apache/spark/blob/branch-1.1/dev/create-release/translate-contributors.py">this other script</a>,
+which fetches potential replacements from Github and JIRA. For instance:</p>
+
+<pre><code>$ cd release-spark/dev/create-release
+# Set RELEASE_TAG and PREVIOUS_RELEASE_TAG
+$ vim generate-contributors.py
+# Generate initial contributors list, likely with warnings
+$ ./generate-contributors.py
+# Set JIRA_USERNAME, JIRA_PASSWORD, and GITHUB_API_TOKEN
+$ vim release-spark/dev/translate-contributors.py
+# Translate names generated in the previous step, reading from known_translations if necessary
+$ ./translate-contributors.py
+</code></pre>
+
+<p>Additionally, if you wish to give more specific credit for developers of larger patches, you may 
+use the the following commands to identify large patches. Extra care must be taken to make sure 
+commits from previous releases are not counted since git cannot easily associate commits that 
+were back ported into different branches.</p>
+
+<pre><code># Determine PR numbers closed only in the new release
+$ git log v1.1.1 | grep "Closes #" | cut -d " " -f 5,6 | grep Closes | sort &gt; closed_1.1.1
+$ git log v1.1.0 | grep "Closes #" | cut -d " " -f 5,6 | grep Closes | sort &gt; closed_1.1.0
+$ diff --new-line-format="" --unchanged-line-format="" closed_1.1.1 closed_1.1.0 &gt; diff.txt
+ 
+# Grep expression with all new patches
+$ EXPR=$(cat diff.txt | awk '{ print "\\("$1" "$2" \\)"; }' | tr "\n" "|" | sed -e "s/|/\\\|/g" | sed "s/\\\|$//")
+ 
+# Contributor list
+$ git shortlog v1.1.1 --grep "$EXPR" &gt; contrib.txt
+ 
+# Large patch list (300+ lines)
+$ git log v1.1.1 --grep "$expr" --shortstat --oneline | grep -B 1 -e "[3-9][0-9][0-9] insert" -e "[1-9][1-9][1-9][1-9] insert" | grep SPARK &gt; large-patches.txt
+</code></pre>
+
+<p>Then, update the downloads page, and then the main page with a news item.</p>
+
+<h4>Create an Announcement</h4>
+
+<p>Once everything is working (website docs, website changes) create an announcement on the website 
+and then send an e-mail to the mailing list. Enjoy an adult beverage of your choice, and 
+congratulations on making a Spark release.</p>
