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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
