Subject [jira] [Commented] (YARN-3216) Max-AM-Resource-Percentage should respect node labels
Date Mon, 12 Oct 2015 17:39:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-3216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14953457#comment-14953457

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

bq. now queueResourceLimitsInfo.getQueueCurrentLimit() is common per queue. And a queue may
have 2 or 3 accessible-labels. So I feel I may not be able to use this total value always
like in getAMResourceLimit. Hence I think I need to calculate max-capacity based on label-percentage
per-queue. How do you feel?
You can take a look at {{AbstractCSQueue#getCurrentLimitResource}} as an example to see how
queue calculates max-capacity by partition.

> 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.
