<p>The Apache HBase Translator, known by the name of <b><em>hbase</em></b>, exposes querying functionality to <a href="http://hbase.apache.org/" class="external-link" rel="nofollow">HBase</a> Tables. <a href="http://phoenix.apache.org/" class="external-link" rel="nofollow">Apache Phoenix </a> is a JDBC SQL interface for HBase - see <a href="/author/display/TEIID/Phoenix+Data+Sources" title="Phoenix Data Sources">Phoenix Data Sources</a> that is required for this translator as it pushes down commands into <a href="http://phoenix.apache.org/language/index.html" class="external-link" rel="nofollow">Phoenix SQL</a>.</p>
<p>The DatabaseTimezone property should not be used with this translator.</p>
<p>The HBase Translator doesn't support Joins. Phoenix uses the HBase Table Row ID as the Primary Key, which map to . This Translator is developed with Phoenix 4.3+ for HBase 0.98.1+.</p>
