Subject [jira] [Commented] (YARN-3216) Max-AM-Resource-Percentage should respect node labels
Date Fri, 16 Oct 2015 17:26:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-3216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14961046#comment-14961046

Wangda Tan commented on YARN-3216:
----------------------------------

bq. This can almost match our usecase. and I feel I can file a ticket to handle queue-limit
computation for node partition. Thoughts?
We need it, but I think the problem is, we don't have an API for application to get headroom
for different partitions. IIRC, queue limit is used to compute more precise headroom for application.
We can add the queue-limit computation for node partition after we have such API.

> Currently, max-am-resource-percentage considers default_partition only. When a queue
can access multiple partitions, we should be able to compute max-am-resource-percentage based
on that.
