Subject [jira] [Commented] (YARN-7142) Support placement policy in yarn native services
Date Wed, 11 Apr 2018 17:37:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16434284#comment-16434284

Wangda Tan commented on YARN-7142:
----------------------------------

[~cheersyang], thanks for reviewing this Jira, I agree with [~gsaha]: unlike DS mostly for
dev testing, placement spec of native service should be more clear. The proposed one in this
Jira is clearer than DS spec for end user to use. 

Currently we're planning to backport several dependencies to branch-3.1 so YARN-7142 can be
backported w/o modification and makes native service implementation less divergency between
trunk and branch-3.1. Once YARN-8118 backported, we can backport this one.

> Placement policy exists in the API but is not implemented yet.
> I have filed YARN-8074 to move the composite constraints implementation out of this
phase-1 implementation of placement policy.
