Patch Set 1: (1 comment) http://gerrit.cloudera.org:8080/#/c/4447/1/src/kudu/tools/tool_main.cc File src/kudu/tools/tool_main.cc: PS1, Line 215: // Set the verbosity of the commands to WARNING(2) and above. : // If the user had explicitly specified verbosity, then user's : // verbosity level is honored. Since '--v' depends on minloglevel : // specifying either of them on CLI will override this setting. : if (google::GetCommandLineFlagInfoOrDie("minloglevel").is_default && : google::GetCommandLineFlagInfoOrDie("v").is_default) { : google::SetCommandLineOption("minloglevel", : SimpleItoa(google::GLOG_WARNING).c_str()); : } > One of the motivations of being less verbose here was to keep the output mo I'm arguing for more verbosity in anything that is "unexpected" or "abnormal" which is definitely the case for anything WARN or ERROR. For 'INFO' level, I'm also saying that if anything is 100% expected, we probably shouldn't bother with it. As for machine-parseable output, I have a couple thoughts: 1) any machine consuming the output should be parsing stdout, not stderr (where the logs go) 2) we should be very careful about signing up for any compatibility guarantee on the textual output format of these tools. I'd say in fact we should explicitly document that the output of these tools is _not_ parseable. Otherwise we'll be unable to make improvements over time to make things more human-readable. If machine-parseable output is a goal, we should provide --json options as appropriate. -- To view, visit http://gerrit.cloudera.org:8080/4447 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: I882a340d4c1d205e4e998c888f487b7185000e3c Gerrit-PatchSet: 1 Gerrit-Project: kudu Gerrit-Branch: master Gerrit-Owner: Dinesh Bhat <din...@cloudera.com> Gerrit-Reviewer: Adar Dembo <a...@cloudera.com> Gerrit-Reviewer: Alexey Serbin <aser...@cloudera.com> Gerrit-Reviewer: David Ribeiro Alves <dral...@apache.org> Gerrit-Reviewer: Dinesh Bhat <din...@cloudera.com> Gerrit-Reviewer: Kudu Jenkins Gerrit-Reviewer: Todd Lipcon <t...@apache.org> Gerrit-HasComments: Yes
