Subject [jira] [Commented] (YARN-5524) Yarn live log aggregation does not throw if command line arg is wrong
Date Mon, 15 Aug 2016 19:08:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15421497#comment-15421497

Vrushali C commented on YARN-5524:

Hmm, I get your point about pulling huge logs. Alright, let me think over this and see if
I can add the "unrecognized option" check. 

Also, fixing this means it would break existing behavior for folks who perhaps have been running
(unintentionally) with incorrect/extra options.
