zhihai xu commented on YARN-3395: --------------------------------- I uploaded a patch YARN-3395.000.patch for review. I added two test case in TestFairScheduler Without the change, both tests will fail. > Handle the user name correctly when submit application and use user name as > default queue name. > ----------------------------------------------------------------------------------------------- > > Key: YARN-3395 > URL: https://issues.apache.org/jira/browse/YARN-3395 > Project: Hadoop YARN > Issue Type: Bug > Components: scheduler > Reporter: zhihai xu > Assignee: zhihai xu > Attachments: YARN-3395.000.patch > > > Handle the user name correctly when submit application and use user name as > default queue name. > We should reject the application with an empty or whitespace only user name. > because it doesn't make sense to have an empty or whitespace only user name. > We should remove the trailing and leading whitespace of the user name when we > use user name as default queue name, otherwise it will be rejected by > InvalidQueueNameException from QueueManager. I think this change make sense, > because it will be compatible with queue name convention and also we already > did similar thing for '.' in user name. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
