Subject [jira] [Commented] (YARN-7123) FairScheduler.getResourceCalculator() returns an instance of DefaultResourceCalculator regardless of the configuration
Date Thu, 31 Aug 2017 00:17:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7123?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16148246#comment-16148246

Daniel Templeton commented on YARN-7123:
----------------------------------------

Per offline discussion with [~kasha], it really is an issue, and we don't need it to be configurable.
 Let's just make the default be a {{DominantResourceCalculator}} instance.
