Subject [jira] [Commented] (YARN-4358) Improve relationship between SharingPolicy and ReservationAgent
Date Mon, 23 Nov 2015 19:44:10 GMT

    [ https://issues.apache.org/jira/browse/YARN-4358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15022842#comment-15022842

Carlo Curino commented on YARN-4358:
------------------------------------

(1)/(2) done
(3) as discussed above... agreed to circle back later.
(4) was not address as the two fields are long and the diff might exceed int. 
(5) I implemented the requested changes and refactor a little further the PlanView interface
and InMemoryPlan, getting rid of few methods which were not used anymore as we are switching
to the more efficient RLE-centric requests to the plan.

> At the moment an agent places based on available resources, but has no visibility to
extra constraints imposed by the SharingPolicy. While not all constraints are easily represented
some (e.g., max-instantaneous resources) are easily represented.
