Patch Set 1: (4 comments) Sure wish there was some test coverage on these tools... http://gerrit.cloudera.org:8080/#/c/4013/1/src/kudu/tools/tool_action.h File src/kudu/tools/tool_action.h: PS1, Line 149: ActionArg the name sounds like it's a descriptor for one argument, whereas really it's a descriptor for all of the arguments. Rename to ArgsDescriptor? or ActionArgsInfo? Line 150: struct Arg { I think this being a nested struct is a bit confusing, because, best I can tell, 'ActionArgDescriptor' is an internal thing, and yet now you've got it exposed here looking like it's part of the API. PS1, Line 187: All remaining arguments on the command line will be joined (via single : // space delimiter) to construct the parameter value. I find this odd vs an array.. otherwise you couldn't use this to pass a list of files, where the files may have spaces in their name... eg: kudu log-dump "/home/todd/My Stuff/log-1" "/home/todd/My Stuff/log-2" Also worth noting that this inherently verifies that at least one such argument is passed, right? Line 196: // This parameter will be parsed as a gflag, and thus can be provided by the not clear what "parsed as a gflag" means. Is 'param' the _name_ of a gflag? ie you should have used normal gflag macros to define it, and here you are just referring to it? What happens if you specify an undefined flag? Crash? Does the value of this flag end up in the 'args' map? Or just set into the gflag? -- To view, visit http://gerrit.cloudera.org:8080/4013 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: Ic6aa517ccf1915e4d106bcc5f80a3abfeae03271 Gerrit-PatchSet: 1 Gerrit-Project: kudu Gerrit-Branch: master Gerrit-Owner: Adar Dembo <a...@cloudera.com> Gerrit-Reviewer: Alexey Serbin <aser...@cloudera.com> Gerrit-Reviewer: Dan Burkert <d...@cloudera.com> Gerrit-Reviewer: Kudu Jenkins Gerrit-Reviewer: Todd Lipcon <t...@apache.org> Gerrit-HasComments: Yes
