dan jatnieks reopened CASSANDRA-6777:
-------------------------------------
Re-opening as there does appear to be something to fix in stress to make it
work with java-driver 2.0.
At the moment the 2.1 branch is using {{cassandra-driver-core-2.0.0-rc3}} but I
think when this is updated to the release version of 2.0 this error will occur.
See my previous comment for the proposed stress fix to quote the keyspace name
when calling java-driver {{Metadata#getReplicas}}.
> 2.1 w/java-driver 2.0 and stress write using thrift results in
> ArithmeticException / by zero errors
