> the public method 'has(byte [] family, byte [] qualifier)' internally invoked the private method 'has(byte [] family, byte [] qualifier, long ts, byte [] value, boolean ignoreTS, boolean ignoreValue)' with 'value=new byte[0], ignoreTS=true, ignoreValue=true', but there's a logical error in the body, it'll enter the block
> {code}
> else if (ignoreValue) {
> for (KeyValue kv: list) {
> if (Arrays.equals(kv.getFamily(), family) && Arrays.equals(kv.getQualifier(), qualifier)
> && kv.getTimestamp() == ts) {
> return true;
> }
> }
> }
> {code}
> the expression 'kv.getTimestamp() == ts' in the if conditions should only exist when 'ignoreTS=false', otherwise, the following code will return false!
> {code}
> Put put = new Put(Bytes.toBytes("row-01"));
> put.add(Bytes.toBytes("family-01"), Bytes.toBytes("qualifier-01"),
> 1234567L, Bytes.toBytes("value-01"));
> System.out.println(put.has(Bytes.toBytes("family-01"),
> Bytes.toBytes("qualifier-01")));
> {code}
