Change subject: IMPALA-6741: Add timestamp of fragment instance's status updates ...................................................................... Patch Set 1: (3 comments) Thanks for doing this. http://gerrit.cloudera.org:8080/#/c/12000/1/be/src/runtime/coordinator-backend-state.cc File be/src/runtime/coordinator-backend-state.cc: http://gerrit.cloudera.org:8080/#/c/12000/1/be/src/runtime/coordinator-backend-state.cc@47 PS1, Line 47: "Last report time"; I am nit-picking somewhat, but this is really 'Last received time' from the coordinator's PoV, right? I wonder if it might be better to rename it as such, so that we don't have to explain what the metric means. I don't feel too strongly about this, so I leave it to you. http://gerrit.cloudera.org:8080/#/c/12000/1/tests/query_test/test_observability.py File tests/query_test/test_observability.py: http://gerrit.cloudera.org:8080/#/c/12000/1/tests/query_test/test_observability.py@95 PS1, Line 95: if report_time < report_time_dict.get(node.name, datetime.min): What happens here the first time through, when node.name does not yet exist in the dict? http://gerrit.cloudera.org:8080/#/c/12000/1/tests/query_test/test_observability.py@111 PS1, Line 111: assert time_backward <= ceil(elapsed_time / MIN_NTP_POLL_PERIOD) Should this be num_time_backward? time_backward is a boolean, and shouldn't be used outside of the above while loop. -- To view, visit http://gerrit.cloudera.org:8080/12000 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Iae3dcddc292d694d7003d10ed0caccfceed7d8fa Gerrit-Change-Number: 12000 Gerrit-PatchSet: 1 Gerrit-Owner: Michael Ho <k...@cloudera.com> Gerrit-Reviewer: Balazs Jeszenszky <jes...@gmail.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Michael Ho <k...@cloudera.com> Gerrit-Reviewer: Zoram Thanga <zo...@cloudera.com> Gerrit-Comment-Date: Wed, 28 Nov 2018 21:25:44 +0000 Gerrit-HasComments: Yes
