["Sunil G (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-1963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14488808#comment-14488808 ] 

Sunil G commented on YARN-1963:
-------------------------------

If we introduce a label to represent a specific application priority for configuration and usage purpose, we will get benefits of readability and ease of handling. Also IMO, we may not have a big set of priorities unto 100s o more. Eventhough if we are having more priorities, range of labels will also can help.

> 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.
