> Randomness of stress distributions is not good

> Key: CASSANDRA-12744
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12744
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Reporter: T Jake Luciani
> Assignee: T Jake Luciani
> Priority: Minor
> Labels: stress
> Fix For: 3.0.x
>
>
> The randomness of our distributions is pretty bad. We are using the
> JDKRandomGenerator() but in testing of uniform(1..3) we see for 100
> iterations it's only outputting 3. If you bump it to 10k it hits all 3
> values.
> I made a change to just use the default commons math random generator and now
> see all 3 values for n=10
