Hello Yida Wu, Zoltan Borok-Nagy, Csaba Ringhofer, Impala Public Jenkins, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/21455 to look at the new patch set (#3). Change subject: IMPALA-13075: Cap memory usage for ExprValuesCache at 256KB ...................................................................... IMPALA-13075: Cap memory usage for ExprValuesCache at 256KB ExprValuesCache uses BATCH_SIZE as a deciding factor to set its capacity. It bounds the capacity such that expr_values_array_ memory usage stays below 256KB. This patch tightens that limit to include all memory usage from ExprValuesCache::MemUsage() instead of expr_values_array_ only. Therefore, setting a very high BATCH_SIZE will not push the total memory usage of ExprValuesCache beyond 256KB. Testing: - Add test_join_queries.py::TestExprValueCache. - Pass core tests.
