----------------------------------------

             Summary: ArrayOutOfBounds in cassandra-stress with inverted exponential distribution
                 Key: CASSANDRA-8357
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8357
             Project: Cassandra
          Issue Type: Bug
          Components: Tools
         Environment: 6-node cassandra cluster (2.1.1) on debian.
            Reporter: Jens Preußner
             Fix For: 2.1.1


When using the CQLstress example from GitHub (https://github.com/apache/cassandra/blob/trunk/tools/cqlstress-example.yaml) with an inverted exponential distribution in the insert-partitions field, generated threads fail with
Exception in thread "Thread-20" java.lang.ArrayIndexOutOfBoundsException: 20 at org.apache.cassandra.stress.StressAction$Consumer.run(StressAction.java:307)

See the gist https://gist.github.com/jenzopr/9edde53122554729c852 for the typetest.yaml I used.
The call was:
cassandra-stress user profile=typetest.yaml ops\(insert=1\) -node $NODES
