> Key: HBASE-11788

> Code executed:
> {code}
> @Test
> public void testHbasePutDeleteCell() throws Exception {
> TableName tableName = TableName.valueOf("my_test");
> Configuration configuration = HBaseConfiguration.create();
> HTableInterface table = new HTable(configuration, tableName);

> table.put(put);
> // get row back and assert the values
> Get get = new Get(Bytes.toBytes(rowKey));
> Result result = table.get(get);
> Assert.isTrue(Bytes.toString(result.getValue(familly, Bytes.toBytes("A"))).equals("a"), "Column A value should be a");
> Assert.isTrue(Bytes.toString(result.getValue(familly, Bytes.toBytes("B"))).equals("b"), "Column B value should be b");
> Assert.isTrue(Bytes.toString(result.getValue(familly, Bytes.toBytes("C"))).equals("c"), "Column C value should be c");
> // put the same row again with C column deleted
> put = new Put(Bytes.toBytes(rowKey));
> put.add(familly, Bytes.toBytes("A"), Bytes.toBytes("a"));
> put.add(familly, Bytes.toBytes("B"), Bytes.toBytes("b"));
> put.add(new KeyValue(Bytes.toBytes(rowKey), familly, Bytes.toBytes("C"), HConstants.LATEST_TIMESTAMP, KeyValue.Type.DeleteColumn));
> table.put(put);

> Assert.isTrue(result.getValue(familly, Bytes.toBytes("C")) == null, "Column C should not exists");
> }
> {code}
> This assertion fails, the cell is not deleted but rather the value is empty:
> {code}
> hbase(main):029:0> scan 'my_test'
> ROW COLUMN+CELL
> 12345 column=default:A, timestamp=1408473082290, value=a
> 12345 column=default:B, timestamp=1408473082290, value=b
> 12345 column=default:C, timestamp=1408473082290, value=
> {code}
> This behavior is different than previous 4.8.x Cloudera version and is currently corrupting all hive queries involving is null or is not null operators on the columns mapped to hbase
