[jira] [Commented] (YARN-2745) Extend YARN to support multi-resource packing of tasks

    [ https://issues.apache.org/jira/browse/YARN-2745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14590289#comment-14590289 ] 

Allen Wittenauer commented on YARN-2745:
----------------------------------------

How much of this is actually YARN specific though?  YARN-3819 and YARN-3820 seem like things that HDFS should care about too.  It seems extremely shortsighted not to commit the collection parts into common.

> In this umbrella JIRA we propose an extension to existing scheduling techniques, which accounts for all resources used by a task (CPU, memory, disk, network) and it is able to achieve three competing objectives: fairness, improve cluster utilization and reduces average job completion time.
