> cassandra-stress that is run with a user profile against a cluster will fail to try operations when a node is killed.
> To reproduce:
> # Create a 3 ndoe cluster with ccm
> {code:java}
> ccm create cas-3 --vnodes -n 1 --version=3.11.3``{code}
> # start the cluster
> {code:java}
> ccm start{code}
> # run
> {code:java}
> tools/bin/cassandra-stress user profile=stress.yaml n=100000 ops(insert=1) no-warmup cl=QUORUM -node 127.0.0.2 -rate threads=10{code}
> or run
> {code:java}
> tools/bin/cassandra-stress user profile=stress.yaml n=100000 ops(simple=1) no-warmup cl=QUORUM -node 127.0.0.2 -rate threads=10{code}
> # while the stress is progressing kill a node
> {code:java}
> ccm node1 stop --not-gently{code}
> # wait for cassandra-stress to end
> for the insert case check
