+<h2>(Experimental) Interpreter Execution Hooks</h2>
+
+<p>Zeppelin allows for users to specify additional code to be executed by an
interpreter at pre and post-paragraph code execution. This is primarily useful
if you need to run the same set of code for all of the paragraphs within your
notebook at specific times. Currently, this feature is only available for the
spark and pyspark interpreters. To specify your hook code, you may use
'<code>z.registerHook()</code>. For example, enter the following into one
paragraph:</p>
+<div class="highlight"><pre><code class="python language-python"
data-lang="python"><span class="o">%</span><span class="n">pyspark</span>
+<span class="n">z</span><span class="o">.</span><span
class="n">registerHook</span><span class="p">(</span><span
class="s">"post_exec"</span><span class="p">,</span> <span
class="s">"print 'This code should be executed before the parapgraph
code!'"</span><span class="p">)</span>
+<span class="n">z</span><span class="o">.</span><span
class="n">registerHook</span><span class="p">(</span><span
class="s">"pre_exec"</span><span class="p">,</span> <span
class="s">"print 'This code should be executed after the paragraph
code!'"</span><span class="p">)</span>
+</code></pre></div>
+<p>These calls will not take into effect until the next time you run a
paragraph. In another paragraph, enter
+<code>python
+%pyspark
+print "This code should be entered into the paragraph by the user!"
+</code></p>
+
+<p>The output should be:
+<code>
+This code should be executed before the paragraph code!
+This code should be entered into the paragraph by the user!
+This code should be executed after the paragraph code!
+</code></p>
+
+<p>If you ever need to know the hook code, use <code>z.getHook()</code>:
+<code>python
+%pyspark
+print z.getHook("post_exec")
+</code>
+<code>
+print 'This code should be executed after the paragraph code!'
+</code>
+Any call to <code>z.registerHook()</code> will automatically overwrite what
was previously registered. To completely unregister a hook event, use
<code>z.unregisterHook(eventCode)</code>. Currently only
<code>"post_exec"</code> and <code>"pre_exec"</code> are
valid event codes for the Zeppelin Hook Registry system.</p>
+
+<p>Finally, the hook registry is internally shared by other interpreters in
the same group. This would allow for hook code for one interpreter REPL to be
set by another as follows:</p>
+<div class="highlight"><pre><code class="scala language-scala"
data-lang="scala"><span class="o">%</span><span class="n">spark</span>
+<span class="n">z</span><span class="o">.</span><span
class="n">unregisterHook</span><span class="o">(</span><span
class="s">"post_exec"</span><span class="o">,</span> <span
class="s">"pyspark"</span><span class="o">)</span>
+</code></pre></div>
+<p>The API is identical for both the spark (scala) and pyspark (python)
implementations.</p>
+
+<h3>Caveats</h3>
+
+<p>Calls to <code>z.registerHook("pre_exec", ...)</code> should be
made with care. If there are errors in your specified hook code, this will
cause the interpreter REPL to become unable to execute any code pass the
pre-execute stage making it impossible for direct calls to
<code>z.unregisterHook()</code> to take into effect. Current workarounds
include calling <code>z.unregisterHook()</code> from a different interpreter
REPL in the same interpreter group (see above) or manually restarting the
interpreter group in the UI. </p>
