- Added static order by tests to test_queries.py and QueryTest/sort.test - test_order_by.py also contains tests with static queries that are run with multiple memory limits. - Added stress, scratch disk and failpoints tests - Incorporated Srinath's change that copied all order by with limit tests into the top-n.test file Extra time required: Serial: scratch disk: 42 seconds test queries sort : 77 seconds test sort: 56 seconds sort stress: 142 seconds TOTAL: 5 min 17 seconds Parallel(8 threads): scratch disk: 40 seconds test queries sort: 42 seconds test sort: 49 seconds sort stress: 93 seconds TOTAL: 3 min 44 sec Change-Id: Ic5716bcfabb5bb3053c6b9cebc9bfbbb9dc64a7c Reviewed-on: http://gerrit.ent.cloudera.com:8080/2820 Reviewed-by: Taras Bobrovytsky <tbobrovytsky@cloudera.com> Tested-by: jenkins Reviewed-on: http://gerrit.ent.cloudera.com:8080/3205
