Subject [jira] [Commented] (YARN-5881) Enable configuration of queue capacity in terms of absolute resources
Date Wed, 12 Apr 2017 15:11:42 GMT

    [ https://issues.apache.org/jira/browse/YARN-5881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15966028#comment-15966028

Sunil G commented on YARN-5881:
-------------------------------

I added a new w.i.p patch for configuration piece in YARN-6471.
I thought of discussing here at parent jira for a wider audience.

{code}
yarn.scheduler.capacity.root.default.memory.min-resource
yarn.scheduler.capacity.root.default.memory.max-resource
yarn.scheduler.capacity.root.default.vcores.min-resource
yarn.scheduler.capacity.root.default.vcores.max-resource
{code}

This is a proposed configuration and we are planning to configure min/max for each resource
type separately. This is designed to co-exist with resource profile work as well.

Thoughts? cc/[~leftnoteasy] [~vinodkv] [~vvasudev]

> Currently, Yarn RM supports the configuration of queue capacity in terms of a proportion
to cluster capacity. In the context of Yarn being used as a public cloud service, it makes
more sense if queues can be configured absolutely. This will allow administrators to set usage
limits more concretely and simplify customer expectations for cluster allocation.
