Once "values" is raised to 9, 9 is not a divisor of 1000 so the condition on L1561 never evaluated to true. This resulted in missed flushes which resulted in failures on TSAN build. -- To view, visit http://gerrit.cloudera.org:8080/17376 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Idb2d401ab692decd5bc03b48a96d710546c0039e Gerrit-Change-Number: 17376 Gerrit-PatchSet: 5 Gerrit-Owner: Bankim Bhavsar <ban...@cloudera.com> Gerrit-Reviewer: Andrew Wong <aw...@cloudera.com> Gerrit-Reviewer: Bankim Bhavsar <ban...@cloudera.com> Gerrit-Reviewer: Grant Henke <granthe...@apache.org> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Reviewer: Wenzhe Zhou <wz...@cloudera.com> Gerrit-Comment-Date: Mon, 17 May 2021 22:09:27 +0000 Gerrit-HasComments: Yes
