Above test is failing because of CASSANDRA-13775. Re-running tests with excluding *stress-test* target:

> This is very unintuitive as
> {code}
> cassandra-stress write n=0 -rate threads=1
> {code}
> will do inserts even with *n=0*. I guess most people won't ever run with *n=0* but this is a nice shortcut for creating some schema without using *cqlsh*
> This is happening because we're writing *50k* rows of warmup data as can be seen below:
> {code}
> cqlsh> select count(*) from keyspace1.standard1 ;
>  count
> -------
>  50000
> (1 rows)
> {code}
> We can avoid writing warmup data using 
> {code}
> cassandra-stress write n=0 no-warmup -rate threads=1
> {code}
> but I would still expect to have *0* rows written when specifying *n=0*.
