[jira] [Created] (IMPALA-5805) Impala take CPU high

nilone created IMPALA-5805:
------------------------------

             Summary: Impala take CPU high
                 Key: IMPALA-5805
                 URL: https://issues.apache.org/jira/browse/IMPALA-5805
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 2.2.1
         Environment: Impala 2.2.0-CDH5.4.7，
Redhat 6.4
            Reporter: nilone
         Attachments: impala耗CPU.png

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。
