----------------------------------
Hey Sandy,
Please post a PDF of the doc or some text format so we can track changes in
this jira. Eg upload a new doc with each rev.
Wrt your definition of dominant share, we want to implement weighted DRF here,
and per section 4.3 in the paper:
{noformat}The definition of a dominant share for user i changes to
s_i = max_j{ u_i,j / w_i,j }
where u_i,j is user i’s share of resource j{noformat}
> Add multi-resource scheduling to the fair scheduler

> Key: YARN-326
> URL: https://issues.apache.org/jira/browse/YARN-326
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: scheduler
> Affects Versions: 2.0.2-alpha
> Reporter: Sandy Ryza
> Assignee: Sandy Ryza
>
> With YARN-2 in, the capacity scheduler has the ability to schedule based on
> multiple resources, using dominant resource fairness. The fair scheduler
> should be able to do multiple resource scheduling as well, also using
> dominant resource fairness.
> More details to come on how the corner cases with fair scheduler configs such
> as min and max resources will be handled.
