I assume you have resolved this but if someone else is looking…
You can stop a validation compaction with nodetool stop
AFAIk the only way to stop streaming is to restart the node.
You can also use nodetool setstreamthroughput to reduce the streaming throughput.
We started a repair on one of our nodes without the -pr option. That started a series
of repair on all ranges and we see a ton of streaming activity between lot of nodes in
the cluster. This is putting enormous strain on the cluster. How can I stop all the streaming.
The original repair is already over.
