sql "alter workload policy test_set_var_policy2 properties('enabled'='false');"
def result3 = connect(user = 'test_workload_sched_user', password = '12345', url = context.config.jdbcUrl)
{ Thread.sleep(3000) sql "show variables like '%parallel_pipeline_task_num%';" }
assertEquals("parallel_pipeline_task_num", result3[0][0])
assertEquals("33", result3[0][1])
