If there is a tablet server in the same location as : // the client, it will be the only tablet server scanned. Otherwise, some : // random tablet server will be scanned. nit: move this under the #if defined block below? -- To view, visit http://gerrit.cloudera.org:8080/12138 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I2c6bcc7479c5cf2e17cb6e368ca89a1eb7f21713 Gerrit-Change-Number: 12138 Gerrit-PatchSet: 7 Gerrit-Owner: Will Berkeley <wdberke...@gmail.com> Gerrit-Reviewer: Adar Dembo <a...@cloudera.com> Gerrit-Reviewer: Alexey Serbin <aser...@cloudera.com> Gerrit-Reviewer: Tidy Bot (241) Gerrit-Reviewer: Will Berkeley <wdberke...@gmail.com> Gerrit-Comment-Date: Tue, 08 Jan 2019 06:39:54 +0000 Gerrit-HasComments: Yes
