-</ul>
-
-<h2 id="getting-the-source-code">Getting the source code</h2>
-
-<p>First, you need the Drill source code.</p>
-
-<p>Get the source code on your local drive using Git. Most development is done on
-&quot;master&quot;:</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text">git clone https://git-wip-us.apache.org/repos/asf/drill.git
-</code></pre></div>
-<h2 id="making-changes">Making Changes</h2>
-
-<p>Before you start, send a message to the <a href="http://mail-archives.apache.org/mod_mbox/drill-dev/">Drill developer mailing list</a>, or file a bug
-report in <a href="https://issues.apache.org/jira/browse/DRILL">JIRA</a>. Describe your
-proposed changes and check that they fit in with what others are doing and
-have planned for the project. Be patient, it may take folks a while to
-understand your requirements.</p>
-
-<p>Modify the source code and add some features using your favorite IDE.</p>
-
-<h3 id="coding-convention">Coding Convention</h3>
-
-<p>Please take care about the following points</p>
-
-<ul>
-<li>All public classes and methods should have informative <a href="http://www.oracle.com/technetwork/java/javase/documentation/index-137868.html">Javadoc comments</a>.
-
-<ul>
-<li>Do not use @author tags.</li>
-</ul></li>
-<li>Code should be formatted according to <a href="http://www.oracle.com/technetwork/java/codeconvtoc-136057.html">Sun&#39;s conventions</a>, with one exception:
-
-<ul>
-<li>Indent two (2) spaces per level, not four (4).</li>
-<li>Line length limit is 120 chars, instead of 80 chars.</li>
-</ul></li>
-<li>Contributions should not introduce new Checkstyle violations.</li>
-<li>Contributions should pass existing unit tests.</li>
-<li>New unit tests should be provided to demonstrate bugs and fixes. <a href="http://www.junit.org">JUnit</a> 4.1 is our test framework:
-
-<ul>
-<li>You must implement a class that contain test methods annotated with JUnit&#39;s 4.x @Test annotation and whose class name ends with <code>Test</code>.</li>
-<li>Define methods within your class whose names begin with <code>test</code>, and call JUnit&#39;s many assert methods to verify conditions; these methods will be executed when you run <code>mvn clean test</code>.</li>
-</ul></li>
-</ul>
-
-<h3 id="formatter-configuration">Formatter configuration</h3>
-
-<p>Setting up IDE formatters is recommended and can be done by importing the
-following settings into your browser:</p>
-
-<p>IntelliJ IDEA formatter: <a href="https://cwiki.apache.org/confluence/download/attachments/29687985/intellij-idea-settings.jar?version=1&amp;modificationDate=1381928827000&amp;api=v2">settings
-jar</a></p>
-
-<p>Eclipse: <a href="https://issues.apache.org/jira/secure/attachment/12474245/eclipse_formatter_apache.xml">formatter xml</a></p>
-
-<h3 id="understanding-maven">Understanding Maven</h3>
-
-<p>Drill is built by Maven, a Java build tool.</p>
-
-<ul>
-<li>Good Maven tutorial: <a href="http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html">http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html</a></li>
-</ul>
-
-<p>To build Drill, run</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text">mvn clean install 
-</code></pre></div>
-<h3 id="creating-a-patch">Creating a patch</h3>
-
-<p>Check to see what files you have modified:</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text">git status
-</code></pre></div>
-<p>Add any new files with:</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text">git add .../MyNewClass.java
-git add .../TestMyNewClass.java
-git add .../XXXXXX.q
-git add .../XXXXXX.q.out
-</code></pre></div>
-<p>In order to create a patch, type (from the base directory of drill):</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text">git format-patch origin/master --stdout &gt; DRILL-1234.1.patch.txt
-</code></pre></div>
-<p>This will report all modifications done on Drill sources on your local disk
-and save them into the <em>DRILL-1234.1.patch.txt</em> file. Read the patch file.
-Make sure it includes ONLY the modifications required to fix a single issue.</p>
-
-<p>Please do not:</p>
-
-<ul>
-<li>reformat code unrelated to the bug being fixed: formatting changes should be separate patches/commits.</li>
-<li>comment out code that is now obsolete: just remove it.</li>
-<li>insert comments around each change, marking the change: folks can use subversion to figure out what&#39;s changed and by whom.</li>
-<li>make things public which are not required by end users.</li>
-</ul>
-
-<p>Please do:</p>
-
-<ul>
-<li>try to adhere to the coding style of files you edit;</li>
-<li>comment code whose function or rationale is not obvious;</li>
-<li>update documentation (e.g., <em>package.html</em> files, this wiki, etc.)</li>
-</ul>
-
-<h3 id="updating-a-patch">Updating a patch</h3>
-
-<p>For patch updates, our convention is to number them like
-DRILL-1856.1.patch.txt, DRILL-1856.2.patch.txt, etc. And then click the
-&quot;Submit Patch&quot; button again when a new one is uploaded; this makes sure it
-gets back into the review queue. Appending &#39;.txt&#39; to the patch file name makes
-it easy to quickly view the contents of the patch in a web browser.</p>
-
-<h3 id="applying-a-patch">Applying a patch</h3>
-
-<p>To apply a patch either you generated or found from JIRA, you can issue</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text">git am &lt; cool_patch.patch
-</code></pre></div>
-<p>if you just want to check whether the patch applies you can run patch with
---dry-run option.</p>
-
-<h3 id="review-process">Review Process</h3>
-
-<ul>
-<li>Use Hadoop&#39;s <a href="http://wiki.apache.org/hadoop/CodeReviewChecklist">code review checklist</a> as a rough guide when doing reviews.</li>
-<li>In JIRA, use attach file to notify that you&#39;ve submitted a patch for that issue.</li>
-<li>Create a Review Request in <a href="https://reviews.apache.org/r/">Review Board</a>. The review request&#39;s name should start with the JIRA issue number (e.g. DRILL-XX) and should be assigned to the &quot;drill-git&quot; group.</li>
-<li>If a committer requests changes, set the issue status to &#39;Resume Progress&#39;, then once you&#39;re ready, submit an updated patch with necessary fixes and then request another round of review with &#39;Submit Patch&#39; again.</li>
-<li>Once your patch is accepted, be sure to upload a final version which grants rights to the ASF.</li>
-</ul>
-
-<h2 id="where-is-a-good-place-to-start-contributing?">Where is a good place to start contributing?</h2>
-
-<p>After getting the source code, building and running a few simple queries, one
-of the simplest places to start is to implement a DrillFunc.<br>
-DrillFuncs is way that Drill express all scalar functions (UDF or system).<br>
-First you can put together a JIRA for one of the DrillFunc&#39;s we don&#39;t yet have
-but should (referencing the capabilities of something like Postgres<br>
-or SQL Server). Then try to implement one.</p>
-
-<p>One example DrillFunc:</p>
-
-<p><a href="https://github.com/apache/drill/blob/3f93454f014196a4da198ce012b605b70081fde0/exec/java-exec/src/main/codegen/templates/ComparisonFunctions.java">ComparisonFunctions.java</a></p>
-
-<p>Also one can visit the JIRA issues and implement one of those too. </p>
-
-<p>More contribution ideas are located on the <a href="/drill/docs/apache-drill-contribution-ideas">Contribution Ideas</a> page.</p>
-
-<h3 id="contributing-your-work">Contributing your work</h3>
-
-<p>Finally, patches should be <em>attached</em> to an issue report in
-<a href="http://issues.apache.org/jira/browse/DRILL">JIRA</a> via the <strong>Attach File</strong>
-link on the issue&#39;s JIRA. Please add a comment that asks for a code review.
-Please note that the attachment should be granted license to ASF for inclusion
-in ASF works (as per the <a href="http://www.apache.org/licenses/LICENSE-2.0">Apache
-License</a>.</p>
-
-<p>Folks should run <code>mvn clean install</code> before submitting a patch. Tests should
-all pass. If your patch involves performance optimizations, they should be
-validated by benchmarks that demonstrate an improvement.</p>
-
-<p>If your patch creates an incompatibility with the latest major release, then
-you must set the <strong>Incompatible change</strong> flag on the issue&#39;s JIRA &#39;and&#39; fill
-in the <strong>Release Note</strong> field with an explanation of the impact of the
-incompatibility and the necessary steps users must take.</p>
-
-<p>If your patch implements a major feature or improvement, then you must fill in
-the <strong>Release Note</strong> field on the issue&#39;s JIRA with an explanation of the
-feature that will be comprehensible by the end user.</p>
-
-<p>A committer should evaluate the patch within a few days and either: commit it;
-or reject it with an explanation.</p>
-
-<p>Please be patient. Committers are busy people too. If no one responds to your
-patch after a few days, please make friendly reminders. Please incorporate
-other&#39;s suggestions into your patch if you think they&#39;re reasonable. Finally,
-remember that even a patch that is not committed is useful to the community.</p>
-
-<p>Should your patch receive a &quot;-1&quot; select the <strong>Resume Progress</strong> on the issue&#39;s
-JIRA, upload a new patch with necessary fixes, and then select the <strong>Submit
-Patch</strong> link again.</p>
-
-<p>Committers: for non-trivial changes, it is best to get another committer to
-review your patches before commit. Use <strong>Submit Patch</strong> link like other
-contributors, and then wait for a &quot;+1&quot; from another committer before
-committing. Please also try to frequently review things in the patch queue.</p>
-
-<h2 id="jira-guidelines">JIRA Guidelines</h2>
-
-<p>Please comment on issues in JIRA, making their concerns known. Please also
-vote for issues that are a high priority for you.</p>
-
-<p>Please refrain from editing descriptions and comments if possible, as edits
-spam the mailing list and clutter JIRA&#39;s &quot;All&quot; display, which is otherwise
-very useful. Instead, preview descriptions and comments using the preview
-button (on the right) before posting them. Keep descriptions brief and save
-more elaborate proposals for comments, since descriptions are included in
-JIRA&#39;s automatically sent messages. If you change your mind, note this in a
-new comment, rather than editing an older comment. The issue should preserve
-this history of the discussion.</p>
