Subject [jira] [Commented] (YARN-6789) new api to get all supported resources from RM
Date Fri, 11 Aug 2017 14:07:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6789?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16123385#comment-16123385

Varun Vasudev commented on YARN-6789:
-------------------------------------

Strongly disagree with not having units. Today if a cluster wants to do scheduling in milliVcores,
it requires updates to the RM, the NM and breaks *every* job that runs on the cluster because
every job must be re-configured to run in milliVcores. Kubernetes has had support for units
from the beginning, I don't see why YARN shouldn't have support for units as well.
