<p>Moves data from Vertia to Hive. The operator runs
your query against Vertia, stores the file locally
before loading it into a Hive table. If the <code class="docutils literal notranslate"><span class="pre">create</span></code> or
<code class="docutils literal notranslate"><span class="pre">recreate</span></code> arguments are set to <code class="docutils literal notranslate"><span class="pre">True</span></code>,
a <code class="docutils literal notranslate"><span class="pre">CREATE</span> <span class="pre">TABLE</span></code> and <code class="docutils literal notranslate"><span class="pre">DROP</span> <span class="pre">TABLE</span></code> statements are generated.
Hive data types are inferred from the cursor’s metadata.
Note that the table generated in Hive uses <code class="docutils literal notranslate"><span class="pre">STORED</span> <span class="pre">AS</span> <span class="pre">textfile</span></code>
which isn’t the most efficient serialization format. If a
large amount of data is loaded and/or if the table gets
queried considerably, you may want to use this operator only to
stage the data into a temporary table before loading it into its
final destination using a <code class="docutils literal notranslate"><span class="pre">HiveOperator</span></code>.</p>
