title: Sqoop import from MariaDB into HBase with custom row keys
body: <p>I'm using Sqoop to import columns from a MySQL table into a HBase table and I want to add a field to the row key that isn't a column.</p>
  
  <p>I know you can set composite row keys with:</p>
  
  <pre><code>sqoop import ... --hbase-row-key &lt;col1&gt;,&lt;col2&gt;
  </code></pre>
  
  <p>but I want something like &lt; custom value >_&lt; col1 >_&lt; col2 >.</p>
  
  <p>If sqoop import doesn't allow it, is it possible to edit the row keys afterward to add that field ?</p>
