Subject [jira] [Commented] (YARN-1963) Support priorities across applications within the same queue
Date Sat, 24 Jan 2015 01:03:40 GMT

    [ https://issues.apache.org/jira/browse/YARN-1963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14290300#comment-14290300

Eric Payne commented on YARN-1963:
----------------------------------

+1 on using numbers and not labels. It seems that the use of labels adds more complexity in
mapping, sending via PB, and converting back to numbers, and does not seem to add much clarity.

> It will be very useful to support priorities among applications within the same queue,
particularly in production scenarios. It allows for finer-grained controls without having
to force admins to create a multitude of queues, plus allows existing applications to continue
using existing queues which are usually part of institutional memory.
