[jira] [Commented] (YARN-1963) Support priorities across
applications within the same queue
[ https://issues.apache.org/jira/browse/YARN-1963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15451780#comment-15451780 ]
stefanlee commented on YARN-1963:
---------------------------------
[~sunilg] Thanks your jira, i have a doubt that "creating multiple queues and making
users submit applications to higher priority and lower priority queues separately" in your doc,it means we create multiple queues, e.g. queue A and queue B,then label A higher priority queue ,label B lower priority queue, after that ,user can submit higher priority application to A ?but i look up your code ,it means user can submit different priority application to same queue and the queue has a default priority,the cluster has a max priority.

> 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.
