[jira] [Commented] (HADOOP-5726) Remove pre-emption from the capacity scheduler code base

    [ https://issues.apache.org/jira/browse/HADOOP-5726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13399476#comment-13399476 ] 

Ryan Hennig commented on HADOOP-5726:
-------------------------------------

Are there any plans to re-add pre-emption to the Capacity Scheduler?  Or any best practices for using the CS in a way that allows high-priority, time-sensitive jobs to have adequate resources when needed, without sacrificing utilization at other times?

> In an effort to simplify the code base, we would like to remove the pre-emption related code in the capacity scheduler. We would reintroduce this (possibly with some revisions to the original design) after a while. This will be an incompatible change. Any objections ?
