new version of Cassandra-stress doesn't support random read benchmark?

[Min Zhou]

Hi all,



Seems there is only one implementation of the getKey() , it's
in PredefinedOperation.java  cassandra branch 2.2.0-beta1


    protected ByteBuffer getKey()
    {
        return (ByteBuffer) partitions.get(0).getPartitionKey(0);
    }

The read operations will just the same key for each iteration, since it
will lead 100% cache hit on the storage side, the result throughput will be
very high.

please correct me if i was wrong.
