title: how to get 2 columns from different column family while scaning hbase with jav api
body: <p>I am trying to get 2 columns from 2 different column family and not able to do it. I am doing a time range scan on column bb</p>
  
  <pre><code>sc.addColumn("A", aa);
   sc.addColumn("B", "bb");
   sc.setTimeRange(from, to);
  
   Scan scan = sc.getScan();
  
   ResultScanner scanner = table.getScanner(scan);
  </code></pre>
  
  <p>I am able to get cloumn bb but not aa from ResultScanner object.</p>
  
  <p>Say column aa is rowkey for that and if I can get rowkey anyhow when doing a time range scan on column bb. Or there any other better way.</p>
  
  <p>Any help would be appreciated.</p>
