> I know the option "-mem_limit" can make effect on memory limit,but I cannot
> find any option with CPU limit,such as thread counts per-impalad instance。
> Can "be_service_threads" or "fe_service_threads" make some effect?
> I found the impalad process can use more than 20 cores sometimes, this lead
> high system load。Our impala version is 2.2.0-CDH5.4.7 ,and we're not ready to
> use "Llama" to manage resource with yarn。
