Description

The test consistently takes over an hour to run

http://sandbox.jenkins.cloudera.com/job/impala-external-gerrit-verify-merge/lastSuccessfulBuild/testReport/stress.test_mini_stress/history/?

that's about 1/3 the time of the gvm. As far as I can tell the only query the test runs is

Query: select count(*) from (select * from lineitem limit 10) p
+----------+
| count(*) |
+----------+
| 10       |
+----------+
Fetched 1 row(s) in 0.12s

which is really fast. Jenkins says it takes ~1 min to run that query 5 times. We should figure out why that is so slow.
