             Summary: single_node_perf_run performance has high variability
                 Key: IMPALA-6161
                 URL: https://issues.apache.org/jira/browse/IMPALA-6161
             Project: IMPALA
          Issue Type: Bug
          Components: Perf Investigation
            Reporter: Jim Apple


single_node_perf_run has different run caharacteristics for the queries 
depening on which order they are run in. See

https://jenkins.impala.io/view/Experimental/job/perf-AB-test/148/parameters/

https://jenkins.impala.io/view/Experimental/job/perf-AB-test/149/parameters/

https://jenkins.impala.io/view/Experimental/job/perf-AB-test/151/parameters/

https://jenkins.impala.io/view/Experimental/job/perf-AB-test/152/parameters/

When the order of the hashes changes, the performance changes as well.
