title: HBase Scan api with multiple filtering conditions
body: <p>I am very new to HBase api and seeing some strange results when doing the following.</p>
  
  <p>We are trying to scan based on multiple filters. I want to pass all the filter conditions.  I am using the below code.</p>
  
  <pre><code>FilterList filterList = new FilterList(FilterList.Operator.MUST_PASS_ALL);
  Filter pageFilter = new PageFilter(5000);
  filterList.addFilter(pageFilter);
  SingleColumnValueFilter filterOne = new SingleColumnValueFilter(Bytes.toBytes(COLUMN_FAMILY),
                  Bytes.toBytes(COLUMN_NAME1), CompareOp.EQUAL, Bytes.toBytes(value1));
  filterList.addFilter(filterOne);
  SingleColumnValueFilter filterTwo = new SingleColumnValueFilter(Bytes.toBytes(COLUMN_FAMILY),
                  Bytes.toBytes(COLUMN_NAME2), CompareOp.EQUAL, Bytes.toBytes(value2));
  filterList.addFilter(filterOne);
  filterList.addFilter(filterTwo);
  
  //Scan
  Scan scan = new Scan();
  scan.setFilter(filterList);
  Result result;
  try {
              scanner = hTable.getScanner(scan);
          } catch (IOException e) {
              // TODO Auto-generated catch block
              e.printStackTrace();
          }
  while ((result = scanner.next()) != null) {
    //print the result.
  }
  //If I am adding multiple SingleColumnValueFilter and I am not doing a addCoulmn() to the scan I am not getting any result even though there are records.
  
  //If I am adding a column to scan then I am seeing results. Initially the result set is matching my filter condition but if I am running for bigger hbase data set then I am seeing bad results.
  
  //If I am adding multiple addCoulmn() to my scan then I am not seeing any result
  </code></pre>
  
  <p>I try to look for proper example but none of them seem to be working. Any help in this direction is greatly appreciated. Thanks in advance.</p>
