This brings two adjustments: First, it changes the expected number of connections for Scylla clusters since with multiple shards driver will usually open more connections. Second, the checks for number of open channels now ignore the target port on the cluster. Any channel matchin the address without port will now count. This helps to correctly count connections to ccm made Scylla clusters which can use different ports depending on circumstances. For example with advanced shard awareness driver will target different port than in non-shard aware case.
When running this test with newer Scylla, the drop keyspace query times out. This is because the cluster lacks raft quorum, although the returned `OperationTimedOutException` does not inform about that. To observe this you need to enable debug logging and then you may find message like this one before the exception: ``` [cluster2-nio-worker-3] DEBUG com.datastax.driver.core.Connection - Connection[/127.0.1.2:40269-1, inFlight=0, closed=false] Response received on stream 832 but no handler set anymore (either the request has timed out or it was closed due to another error). Received message is ERROR SERVER_ERROR: group [e4fdf001-521a-11f0-b1fb-7d275bcabf53] raft operation [read_barrier] timed out, there is no raft quorum, total voters count 2, alive voters count 1, dead voters [127.0.1.1] ``` Increasing the number of nodes to 3 allows the cluster to maintain the raft quorum and does not impact the test itself.
