Change subject: [location_awareness] Register client with location when connect to cluster ...................................................................... Patch Set 6: (4 comments) http://gerrit.cloudera.org:8080/#/c/11923/6/src/kudu/master/master-test.cc File src/kudu/master/master-test.cc: http://gerrit.cloudera.org:8080/#/c/11923/6/src/kudu/master/master-test.cc@1626 PS6, Line 1626: TestConnectToMasterRegisterLocation It would be nice to have a scenario to verify how the system behaves in case if the location-assignment command returns an error. http://gerrit.cloudera.org:8080/#/c/11923/6/src/kudu/master/master_service.cc File src/kudu/master/master_service.cc: http://gerrit.cloudera.org:8080/#/c/11923/6/src/kudu/master/master_service.cc@536 PS6, Line 536: resp->set_client_location(location); generic/paranoid nit: if GetClientLocation() didn't return Status::OK(), I think we should not try to set the location field in the response. I think that's one of the best practices if you think of the GetClientLocation() as a black box and don't have an assurance that the 'location' out argument is not touched in case of non-OK return code from the function. http://gerrit.cloudera.org:8080/#/c/11923/6/src/kudu/master/ts_descriptor.cc File src/kudu/master/ts_descriptor.cc: http://gerrit.cloudera.org:8080/#/c/11923/6/src/kudu/master/ts_descriptor.cc@410 PS6, Line 410: if (!location_mapping_cmd.empty()) { style code/readability nit: prefer the 'return early' style here, i.e. if (location_mapping_cmd.empty()) { return Status::OK(); } // Continue with the logic specific to the process of running the location command ...
