Subject [jira] [Commented] (YARN-4358) Improve relationship between SharingPolicy and ReservationAgent
Date Mon, 23 Nov 2015 18:43:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-4358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15022698#comment-15022698

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

[~asuresh] thanks for the comments. I agree with them. 

In particular regarding (3), we are currently slightly abusing the use of RLESparseResourceAllocation
to efficiently track time-varying quantities (which are not memory/core resources). As YARN-3926
lands, this can be made look much cleaner as we will be able to define new logical resources.


I will address your comments and upload a new version soon.

> 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.
