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 reduces the memory limit for the following query in test_exchange_mem_usage_scaling test from 170MB to 164MB to reduce the chance of not detecting a memory allocation failure. set mem_limit=<limit_in_mb> 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 a test with 500 executions of the above query with the memory limit set to 164MB, there were 500 memory allocation failures in total (one in each execution), and a total of 266 of them from Exchange Node #4. Testing: Ran the query in question individually; Ran TestExchangeMemUsage.test_exchange_mem_usage_scaling test; Ran core tests.
