Subject [jira] [Updated] (YARN-1011) [Umbrella] Schedule containers based on utilization of currently allocated containers
Date Wed, 13 Jan 2016 18:43:40 GMT

     [ https://issues.apache.org/jira/browse/YARN-1011?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Karthik Kambatla updated YARN-1011:
-----------------------------------
    Attachment: yarn-1011-design-v2.pdf

Based on the comments here and learnings from the paper Bikas pointed out, I have updated
the design with more details. Most of the new details are in the section named Scheduling
(Section 3.1 in page 2). 

[~bikassaha], [~nroberts], [~leftnoteasy], [~elgoiri] - could you give it a quick read through,
and see if it is missing any major things. I am fairly certain we ll learn more as we implement/use
the feature.

> Currently RM allocates containers and assumes resources allocated are utilized.
> RM can, and should, get to a point where it measures utilization of allocated containers
and, if appropriate, allocate more (speculative?) containers.
