            assertTrue("Column D value should be d",
              Bytes.toString(result.getValue(family, Bytes.toBytes("D"))).equals("d"));
            // put the same row again with C column deleted
            put = new Put(rowKey);
            put.add(family, Bytes.toBytes("A"), Bytes.toBytes("a1"));
            put.add(family, Bytes.toBytes("B"), Bytes.toBytes("b1"));
            KeyValue marker = new KeyValue(rowKey, family, Bytes.toBytes("C"),
              HConstants.LATEST_TIMESTAMP, KeyValue.Type.DeleteColumn); 
            put.add(marker);
      	  put.add(family, Bytes.toBytes("D"), Bytes.toBytes("d1"));
            table.put(put);
      
            // get row back and assert the values
            get = new Get(rowKey);
            result = table.get(get);
            assertTrue("Column A value should be a1",
              Bytes.toString(result.getValue(family, Bytes.toBytes("A"))).equals("a1"));
            assertTrue("Column B value should be b1",
              Bytes.toString(result.getValue(family, Bytes.toBytes("B"))).equals("b1"));
            assertTrue("Column C should not exist",
              result.getValue(family, Bytes.toBytes("C")) == null);
      	  assertTrue("Column D value should be d1",
              Bytes.toString(result.getValue(family, Bytes.toBytes("D"))).equals("d1"));
          }
      

      This assertion fails, the cell D is also deleted
