Community</h1>
+
+<p>This guide documents the best way to make various types of contribution to
Apache Toree, including what is required before submitting a code change and
how to properly merge them.</p>
+
+<p>Contributing to Toree doesnât just mean writing code. Helping testing and
reviewing pull requests and improving documentation are also welcome. In fact,
proposing significant code changes usually requires first gaining experience
and credibility within the community by helping in other ways. This is also a
guide to becoming an effective contributor.</p>
+
+<h2 id="contributing-by-helping-other-users">Contributing by Helping Other
Users</h2>
+
+<p>A great way to contribute to Toree is to help answer user questions on the
<a
href="https://www.mail-archive.com/dev@toree.incubator.apache.org/";>d...@toree.incubator.apache.org</a>
mailing list. There are always many new users; taking a few minutes to help
answer a question is a very valuable community service.</p>
+
+<p>Contributors should subscribe to this list and follow it in order to keep
up to date on whatâs happening in Toree. Answering questions is an excellent
and visible way to help the community, which also demonstrates your
expertise.</p>
+
+<h2 id="contributing-by-testing-releases">Contributing by Testing Releases</h2>
+
+<p>Toreeâs release process is community-oriented, and members of the
community can vote on new releases on the <a
href="https://www.mail-archive.com/dev@toree.incubator.apache.org/";>d...@toree.incubator.apache.org</a>
mailing list. Toree users are invited to subscribe to this list to receive
announcements of release vote, and test Toree extensions on newer release and
provide feedback on any performance or correctness issues found in the newer
release.</p>
+
+<!--
+
+-->
+
+<h2 id="contributing-code-changes">Contributing code changes</h2>
+
+<p>Please review the preceding section before proposing a code change. This
section documents how to do so:</p>
+
+<p><img src="/assets/images/important.png" height="22" width="22" />
<strong>When you contribute code, you affirm that the contribution is your

+
+<h3 id="jira">JIRA</h3>
+
+<p>Toree uses JIRA to track issues, including bugs and improvements, and uses
Github pull requests to manage the review and merge of specific code changes.
That is, JIRAs are used to describe what should be fixed or changed, and
high-level approaches, and pull requests describe how to implement that change
in the projectâs source code. For example, major design decisions are
discussed in JIRA.</p>
+
+<ol>
+ <li>Find the existing <a
href="https://issues.apache.org/jira/browse/TOREE";>TOREE JIRA</a> that the
change pertains to.
+ <ul>
+ <li>Do not create a new JIRA if creating a change to address an existing
issue in JIRA; add to the existing discussion and work instead</li>
+ <li>Look for existing pull requests that are linked from the JIRA, to
understand if someone is already working on the JIRA</li>
+ </ul>
+ </li>
+ <li>If the change is new, then it usually needs a new JIRA. However, trivial
changes, where the what should change is virtually the same as the how it
should change do not require a JIRA. Example: âFix typos in Foo
scaladocâ</li>
+ <li>If required, create a new JIRA:
+ <ul>
+ <li>Provide a descriptive Title. âUpdate web UIâ or âProblem in
schedulerâ is not sufficient. âKafka Streaming support fails to handle
empty queue in YARN cluster modeâ is good.</li>
+ <li>Write a detailed Description. For bug reports, this should ideally
include a short reproduction of the problem. For new features, it may include a
design document.</li>
+ <li>Set required fields:</li>
+ <li><strong>Issue Type</strong>. Generally, Bug, Improvement and New
Feature are the only types used in Toree.</li>
+ <li><strong>Priority</strong>. Set to Major or below; higher priorities
are generally reserved for committers to set. JIRA tends to unfortunately
conflate âsizeâ and âimportanceâ in its Priority field values. Their
meaning is roughly:
+ <ul>
+ <li>Blocker: pointless to release without this change as the release
would be unusable to a large minority of users</li>
+ <li>Critical: a large minority of users are missing important
functionality without this, and/or a workaround is difficult</li>
+ <li>Major: a small minority of users are missing important
functionality without this, and there is a workaround</li>
+ <li>Minor: a niche use case is missing some support, but it does not
affect usage or is easily worked around</li>
+ <li>Trivial: a nice-to-have change but unlikely to be any problem in
practice otherwise</li>
+ </ul>
+ </li>
+ <li><strong>Component</strong></li>
+ <li><strong>Affects Version</strong>. For Bugs, assign at least one
version that is known to exhibit the problem or need the change</li>
+ <li>Do not set the following fields:</li>
+ <li><strong>Fix Version</strong>. This is assigned by committers only
when resolved.</li>
+ <li><strong>Target Version</strong>. This is assigned by committers to
indicate a PR has been accepted for possible fix by the target version.</li>
+ <li>Do not include a patch file; pull requests are used to propose the
actual change.</li>
+ </ul>
+ </li>
+ <li>If the change is a large change, consider inviting discussion on the
issue at d...@toree.incubator.apache.org first before proceeding to implement
the change.</li>
+</ol>
+
+<h3 id="before-creating-a-pull-request">Before creating a Pull Request</h3>
+
+<p>Fork the Github repository at https://github.com/apache/incubator-toree and
clone your fork if you havenât already</p>
+
+<ul>
+ <li>If you havenât done so, please set upstream as described in <a
href="https://help.github.com/articles/configuring-a-remote-for-a-fork/";>GitHub
Documentation</a></li>
+</ul>
+
+<p>Make sure you have the most up to date code</p>
+
+<p>Make sure you do not have any uncommitted changes and rebase master with
latest changes from upstream:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git fetch upstream
+git checkout master
+git rebase upstream/master
+</code></pre>
+</div>
+
+<p>Now you should rebase your branch with master, to receive the upstream
changes</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>git checkout branch
+git rebase master
+</code></pre>
+</div>
+
+<p>In both cases, you can have conflicts:</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>error: could not
apply fa39187... something to add to patch A
+
+When you have resolved this problem, run "git rebase --continue".
+If you prefer to skip this patch, run "git rebase --skip" instead.
+To check out the original branch and stop rebasing, run "git rebase --abort".
+Could not apply fa39187f3c3dfd2ab5faa38ac01cf3de7ce2e841... Change fake file
+</code></pre>
+</div>
+
+<p>Here, Git is telling you which commit is causing the conflict (fa39187).
Youâre given three choices:</p>
+
+<ul>
+ <li>You can run <strong>git rebase âabort</strong> to completely undo the
rebase. Git will return you to your branchâs state as it was before git
rebase was called.</li>
+ <li>You can run <strong>git rebase âskip</strong> to completely skip the
commit. That means that none of the changes introduced by the problematic
commit will be included. It is very rare that you would choose this option.</li>
+ <li>You can fix the conflict.</li>
+</ul>
+
+<p>To fix the conflict, you can follow <a
href="https://help.github.com/articles/resolving-a-merge-conflict-from-the-command-line";>the
standard procedures for resolving merge conflicts from the command line</a>.
When youâre finished, youâll need to call <strong>git rebase
âcontinue</strong> in order for Git to continue processing the rest of the
rebase.</p>
+
+<h3 id="creating-a-pull-request">Creating a Pull Request</h3>
+
+<ol>
+ <li>Create a new branch, push commits to the branch.</li>
+ <li>Consider whether documentation or tests need to be added or updated as
part of the change, and add them as needed.</li>
+ <li>Open a pull request against the master branch of apache/incubator-toree.
(Only in special cases would the PR be opened against other branches.)
+ <ul>
+ <li>The PR title should be of the form [TOREE-xxxx] Title, where
TOREE-xxxx is the relevant JIRA number and Title may be the JIRAâs title or a
more specific title describing the PR itself.</li>
+ <li>If the pull request is still a work in progress, and so is not ready
to be merged, but needs to be pushed to Github to facilitate review, then add
[WIP] after the component.</li>
+ </ul>
+ </li>
+ <li>Follow <a href="http://chris.beams.io/posts/git-commit/";>The 7 rules for
a great commit message</a>
+ <ul>
+ <li>Separate subject from body with a blank line</li>
+ <li>Limit the subject line to 50 characters</li>
+ <li>Capitalize the subject line</li>
+ <li>Do not end the subject line with a period</li>
+ <li>Use the imperative mood in the subject line</li>
+ <li>Wrap the body at 72 characters</li>
+ <li>Use the body to explain what and why vs. how</li>
+ </ul>
+ </li>
+</ol>
+
+<p>Below is an example of a good commit message</p>
+
+<div class="highlighter-rouge"><pre class="highlight"><code>[TOREE-130]
Performance enhancements for decision tree
+
+Generate Matrix with random values through local memory
+if there is sufficient memory.
+</code></pre>
+</div>
+
+<h3 id="code-review-criteria">Code Review Criteria</h3>
+<p>Before considering how to contribute code, itâs useful to understand how
code is reviewed, and why changes may be rejected. Simply put, changes that
have many or large positives, and few negative effects or risks, are much more
likely to be merged, and merged quickly. Risky and less valuable changes are
very unlikely to be merged, and may be rejected outright rather than receive
iterations of review.</p>
+
+<p><strong>Positives</strong></p>
+
+<ul>
+ <li>Fixes the root cause of a bug in existing functionality</li>
+ <li>Adds functionality or fixes a problem needed by a large number of
users</li>
+ <li>Simple, targeted</li>
+ <li>Easily tested; has tests</li>
+ <li>Reduces complexity and lines of code</li>
+ <li>Change has already been discussed and is known to committers</li>
+</ul>
+
+<p><strong>Negatives, Risks</strong></p>
+
+<ul>
+ <li>Band-aids a symptom of a bug only</li>
+ <li>Introduces complex new functionality, especially an API that needs to be
supported</li>
+ <li>Adds complexity that only helps a niche use case</li>
+ <li>Changes a public API or semantics (rarely allowed)</li>
+ <li>Adds large dependencies</li>
+ <li>Changes versions of existing dependencies</li>
+ <li>Adds a large amount of code</li>
+ <li>Makes lots of modifications in one âbig bangâ change</li>
+</ul>
+
+<h3 id="the-review-process">The Review Process</h3>
+
+<ul>
+ <li>Other reviewers, including committers, may comment on the changes and
suggest modifications. Changes can be added by simply pushing more commits to
the same branch.</li>
+ <li>Lively, polite, rapid technical debate is encouraged from everyone in
the community. The outcome may be a rejection of the entire change.</li>
+ <li>Reviewers can indicate that a change looks suitable for merging with a
comment such as: âI think this patch looks goodâ. Toree uses the LGTM
convention for indicating the strongest level of technical sign-off on a patch:
simply comment with the word âLGTMâ. It specifically means: âIâve
looked at this thoroughly and take as much ownership as if I wrote the patch
myselfâ. If you comment LGTM you will be expected to help with bugs or
follow-up issues on the patch. Consistent, judicious use of LGTMs is a great
way to gain credibility as a reviewer with the broader community.</li>
+ <li>Sometimes, other changes will be merged which conflict with your pull
requestâs changes. The PR canât be merged until the conflict is resolved.
This can be resolved with âgit fetch originâ followed by âgit merge
origin/masterâ and resolving the conflicts by hand, then pushing the result
to your branch.</li>
+ <li>Try to be responsive to the discussion rather than let days pass between
replies</li>

enable an interactive application against Apache Spark?</h3>

-<p>There are several options to communicate with a Spark cluster, but none
provided the necessary flexibility combined with a API that would work for
them.</p>

+<p>Apache Toree is a kernel for the Jupyter Notebook platform providing
interactively access to Apache Spark. It has been developed using the IPython
protocol, and despite the protocolâs name, the apache Toree currently exposes
the Spark programming model in Scala, Python and R languages.</p>
-<p>Apache Toree was designed in response to our needs to enable applications
that are both interactive and remote to work with Apache Spark. When we first
started connecting applications to Spark, we discovered the existing
interaction mechanisms had serious limitations, such as requiring code to be
bundled in a JAR and writing results out to an external datastore.</p>
+<p>Toree supports a number of types of interactions. In one common case,
applications send snippets of code which are then executed by Spark, and the
results are returned directly to the application. This style of interaction is
what users of Notebooks experience when they evaluate code in cells. Instead of
sending raw code, an application can send magics, which might be commands to
add a JAR to the Spark execution context or a call to execute a shell command
such as âlsâ. Toree provides a well-defined mechanism to associate
functionality with magics, and this is a useful point of extensibility of the
system.</p>
-<p>To overcome these limitations, we wrote the Apache Toree that uses the
IPython protocol. Despite the protocolâs name, the apache Toree is not
limited to supporting just Python, and indeed our first application was a
Notebook for analyzing data with Scala.</p>

communicate with Spark. This is supported through the âComm APIâ which is
useful, for example, when an application needs to repetitively apply the same
function to different data values.</p>
+<p>Applications wanting to work with Spark can be located remotely from a
Spark cluster and use a Apache Toree Client or Jupyter Client to communicate
with a Apache Toree Server running on the cluster, or they can communicate
directly with the Apache Toree Server. Multiple clients/applications can
communicate with a single Kernel which contains a Spark application context,
and this provides a simple form of multi-tenancy.</p>
