Today, at this time of writing, it should be ok: the tests write in a specific directory, and the ports are dynamic. But it's not without danger: what if tomorrow someone creates a bug and hardcodes a port already used by your cluster ? It's unlikely; but it happened in the past. As well, the CPU & memory used by the tests won't be available to your datanode / regionserver, so you doing a kind of load test on this node...
