-----------------------------------
Can you put the second code snippet into a test and provide a patch ?
Thanks
> Put.has() can't determine result correctly

> Key: HBASE-6047
> URL: https://issues.apache.org/jira/browse/HBASE-6047
> Project: HBase
> Issue Type: Bug
> Components: client
> Affects Versions: 0.92.1
> Reporter: Wang Qiang
>
> 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}
