-----------------------------------------------

> Key: CASSANDRA-18051
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18051
> Project: Cassandra
> Issue Type: Task
> Components: Test/dtest/python
> Reporter: Ekaterina Dimitrova
> Priority: Normal
> Fix For: 3.0.x, 3.11.x, 4.0.x, 4.1.x, 5.x
>

> As pointed in CASSANDRA-18001, there are two Python Large DTests that fail
> because of not enough resources with large containers. [~adelapena] looked
> into them and suggested that the tests themselves can be optimized for
> running on Large containers instead of using XLarge containers for only two
> tests from the whole suite.
> {quote}As for the two tests starting nine nodes each,
> {{test_network_topology_strategy}} and
> {{{}test_network_topology_strategy_each_quorum{}}}, I think they were added
> by CASSANDRA-10584 to test multi-DC consistency levels. I wonder if they
> actually need to start 3 data centers with 3 nodes each. Would two data
> centers with 3 nodes be enough to test multi-DC consistency levels with
> multiple data centers? 6 nodes should be doable on Circle with the current
> resources.
> {quote}
> EDIT: On further testing it was noticed that the tests also started failing
> on 3.0 and 3.11 even with XLarge containers and there might be also some
> timing issue further involved and to be investigated.
