Hive provides a mechanism to project structure onto this data and query the data using a SQL-like language called HiveQL. At the same time this language also allows traditional map/reduce programmers to plug in their custom mappers and reducers when it is inconvenient or inefficient to express this logic in HiveQL.</p> <h2>How to use</h2> <p>Basically, you can use</p> <div class="highlight"><pre><code class="sql language-sql" data-lang="sql"><span class="o">%</span><span class="n">hive</span> <span class="k">select</span> <span class="o">*</span> <span class="k">from</span> <span class="n">my_table</span><span class="p">;</span> </code></pre></div> <p>or</p> <div class="highlight"><pre><code class="sql language-sql" data-lang="sql"><span class="o">%</span><span class="n">hive</span><span class="p">(</span><span class="n">etl</span><span class="p">)</span> <span class="c1">-- 'etl' is a ${prefix}</span> <span class="k">select</span> <span class="o">*</span> <span class="k">from</span> <span class="n">my_table</span><span class="p">;</span> </code></pre></div> <p>You can also run multiple queries up to 10 by default. Changing these settings is not implemented yet.</p> <h3>Apply Zeppelin Dynamic Forms</h3> <p>You can leverage <a href="../usage/dynamic_form/intro.html">Zeppelin Dynamic Form</a> inside your queries.
