Varun Vasudev created YARN-2530: ----------------------------------- Summary: MapReduce should take cpu into account when doing headroom calculations Key: YARN-2530 URL: https://issues.apache.org/jira/browse/YARN-2530 Project: Hadoop YARN Issue Type: Improvement Reporter: Varun Vasudev Assignee: Varun Vasudev
Currently the MapReduce AM only uses memory when doing headroom calculation as well calculations about launching reducers. It would be preferable to account for CPU as well if the scheduler on the YARN side is using CPU when scheduling. YARN-2448 lets AMs know what resources are being considered when scheduling. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
