Etienne Chauchot commented on FLINK-28198:
------------------------------------------

Hi [~martijnvisser] I was busy on an urgent matter, I just started to take a 
look. Seems like createTable fails with timeout but not the first create 
keyspace request. Raising once again the timeouts in the cassandra cluster does 
not seem to be the correct move here. All the CQL requests are launched 
synchronously but there might be residual load on the cluster. I'll try to find 
a cluster internal metric and block on its status to ensure the load is ok 
before new tests (in the Before method)
