/**

 * but HBase writes some strings as well, so we need to be able to handle that too
 */
@Test
public void testNonIntegerAnnotations(){
  Span span = getSpan();
  // make sure its less than the length of an integer
  byte[] value = Bytes.toBytes("a");
  byte[] someInt = Bytes.toBytes(1);

  // an annotation that is not an integer
  span.addKVAnnotation(Bytes.toBytes("key"), value);

  // Create the sink and write the span
  TraceMetricSource source = new TraceMetricSource();
