Subject [jira] [Commented] (YARN-5524) Yarn live log aggregation does not throw if command line arg is wrong
Date Thu, 18 Aug 2016 17:14:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15426832#comment-15426832

Naganarasimha G R commented on YARN-5524:

IMO i felt it should be CommandLineParser's responsibility to detect invalid option, if validation
is not happening would it not be better to support it there so that its applicable across
all the CLI Command?
