Change subject: IMPALA-9355: TestExchangeMemUsage.test_exchange_mem_usage_scaling doesn't hit the memory limit ...................................................................... IMPALA-9355: TestExchangeMemUsage.test_exchange_mem_usage_scaling doesn't hit the memory limit This patch restores the previous testing enviroment in which exchange node 5 in the test query shown below reliablly reports memory exceeding limit error. set mem_limit=171520k; set num_scanner_threads=1; select * from tpch_parquet.lineitem l1 join tpch_parquet.lineitem l2 on l1.l_orderkey = l2.l_orderkey and l1.l_partkey = l2.l_partkey and l1.l_suppkey = l2.l_suppkey and l1.l_linenumber = l2.l_linenumber order by l1.l_orderkey desc, l1.l_partkey, l1.l_suppkey, l1.l_linenumber limit 5 In the patch, the memory limit for the entire query is lowered to 164Mb, less than 171520k, the minimum for the query to be accepted after the result spooling is enabled by default. This is achieved by disabling result spooling by setting spool_query_results to false. Testing: 1).
