stress.java performance falls off heavily towards the end
---------------------------------------------------------

                 Key: CASSANDRA-2020
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2020
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Brandon Williams
            Assignee: Pavel Yaskevich
            Priority: Minor
             Fix For: 0.7.1


This is due to threads completing towards the end, such that there aren't enough to fully
stress the cluster.  The main problem here is that stress.java is a straight port of stress.py,
where it each thread run through some range until it's done, and the threads finish at different
times (probably offset by jvm warmup time.)  Instead, a producer/consumer model would work
better.
