Patch Set 1: (1 comment) http://gerrit.cloudera.org:8080/#/c/14234/1/tests/query_test/test_observability.py File tests/query_test/test_observability.py: http://gerrit.cloudera.org:8080/#/c/14234/1/tests/query_test/test_observability.py@675 PS1, Line 675: assert "Hash Table" in runtime_profile : assert "Probes:" in runtime_profile : assert "Travel:" in runtime_profile : assert "HashCollisions:" in runtime_profile : assert "Resizes:" in runtime_profile > would be good to validate that they have valid values - e.g. they are non-z That's a good point. I think it would be easy with the way the code is structured for us to double-count some of these things by moving code around, so some kind of range check might be useful too (I'm fairly flexible on this though since we've generally not validated profile counters for pragmatic reasons). -- To view, visit http://gerrit.cloudera.org:8080/14234 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I1fd875dd1af8031242fd5f5ff554d3a71aaa6f87 Gerrit-Change-Number: 14234 Gerrit-PatchSet: 1 Gerrit-Owner: Yongzhi Chen <yc...@cloudera.com> Gerrit-Reviewer: Bharath Vissapragada <bhara...@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Sahil Takiar <stak...@cloudera.com> Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com> Gerrit-Reviewer: Yongzhi Chen <yc...@cloudera.com> Gerrit-Comment-Date: Mon, 16 Sep 2019 17:38:19 +0000 Gerrit-HasComments: Yes
