This makes debugging very tougher. > This ticket is an effort to introduce more defined states on various parts in > scheduler where it skips/rejects container assignment, activate application > etc. Such information will help user to know whats happening in scheduler. > Attaching a short proposal for initial discussion. We would like to improve > on this as we discuss. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
