Subject [jira] [Commented] (FALCON-1584) Falcon allows invalid hadoop queue name for schedulable feed entities
Date Fri, 08 Jan 2016 04:48:39 GMT

    [ https://issues.apache.org/jira/browse/FALCON-1584?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15088703#comment-15088703

Ajay Yadava commented on FALCON-1584:
-------------------------------------

Thanks for the patch, it looks useful. I have a suggestion, feel free to discount it if it
can not be done easily. Currently the patch only checks that the specified queue exists. This
will solve for the case where the queue name contains a typo(which is not very common e.g.
we use maven resources plugin to replace such parameters). The most common scenario in our
experience is when users specify a queue name but the user doesn't have the permission. If
we can solve that scenario also then the feature will be truly useful.
