Jesus Camacho Rodriguez created HIVE-17510: ----------------------------------------------
Summary: Make comparison of filter predicates in q files deterministic Key: HIVE-17510 URL: https://issues.apache.org/jira/browse/HIVE-17510 Project: Hive Issue Type: Bug Components: Testing Infrastructure Affects Versions: 3.0.0 Reporter: Jesus Camacho Rodriguez Assignee: Jesus Camacho Rodriguez I have been hitting this issue while submitting patches to test HIVE-17432. Basically, the order on which the rewriting might create the children of AND operations is not deterministic. Thus, tests might fail because the created golden file is not the same, thought the test should pass because they just simply do not follow same order: {code} predicate: ((d_year >= 1992) and (d_year <= 1997) and ((c_city = 'UNITED KI1') or (c_city = 'UNITED KI5')) and ((s_city = 'UNITED KI1') or (s_city = 'UNITED KI5'))) (type: boolean) {code} {code} predicate: ((d_year <= 1997) and (d_year >= 1992) and ((c_city = 'UNITED KI1') or (c_city = 'UNITED KI5')) and ((s_city = 'UNITED KI1') or (s_city = 'UNITED KI5'))) (type: boolean) {code} This patches fixes the issue by sorting the children of some expressions (currently AND and OR children) when we run explain plan and we are running in test mode. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
