Subject [jira] [Commented] (YARN-5261) Lease/Reclaim Extension to Yarn
Date Thu, 16 Jun 2016 23:16:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-5261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15334930#comment-15334930

Jason Lowe commented on YARN-5261:

This is very similar work to YARN-5215 and YARN-1011 / YARN-5202.  It would be good to understand
how this is fundamentally different, because at first glance it appears the desired behavior
can be accomplished via one or more of those other efforts.

> In some clusters outside of Yarn, the machines resources are not fully utilized, e.g.,
resource usage is quite low at night.  
> To better utilize the resources while keep the existing SLA of the cluster, Lease/Reclaim
Extension to Yarn is introduced.
