[jira] [Resolved] (YARN-2282) Does hadoop 2.4 support resource
allocation to container for cpu cores ?
[ https://issues.apache.org/jira/browse/YARN-2282?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Zhijie Shen resolved YARN-2282.
-------------------------------
Resolution: Invalid
Please ask questions via hadoop user mailing list: user\@hadoop.apache.org
To this question:
Which scheduler do you use? Would you please check you configuration? Make sure you're using DominantResourceCalculator instead of DefaultResourceCalculator. Otherwise, when normalizing a request, the vcore field will be reset to 1.
