Change subject: IMPALA-10343: increase control_service_queue_mem_limit ...................................................................... IMPALA-10343: increase control_service_queue_mem_limit --control_service_queue_mem_limit is set to 1% by default to increase the maximum size of the queue in typical production deployments. E.g. an Impala daemon with a 50GB memory limit will have a limit of 512MB on the control service queue. Add --control_service_queue_mem_limit_floor_bytes so that this does not have the unintended effect of reducing the memory given to the queue. If the impala daemon has a mem limit of <= 5000MB, this patch has no effect to default behaviour. Testing: This had been previously problematic on a 64 node TPC-DS workload with mt_dop=12 where impalads had ~100GB of memory. Status report RPCs would fail and have to be retried. We tested this new value on the same workload and the retries were avoided.
