Wang Qiang created HBASE-6047:
---------------------------------
Summary: 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
else if (ignoreValue) {
for (KeyValue kv: list) {
if (Arrays.equals(kv.getFamily(), family) &&
Arrays.equals(kv.getQualifier(), qualifier)
&& kv.getTimestamp() == ts) {
return true;
}
}
}
the expression 'kv.getTimestamp() == ts' in the if conditions should only exist
when 'ignoreTS=false', otherwise, the following code will return false!
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")));
