Subject [jira] [Created] (YARN-1212) Add a Scheduling Concepts page to the web doc
Date Wed, 18 Sep 2013 03:13:54 GMT
Sandy Ryza created YARN-1212:
--------------------------------

             Summary: Add a Scheduling Concepts page to the web doc
                 Key: YARN-1212
                 URL: https://issues.apache.org/jira/browse/YARN-1212
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: documentation
    Affects Versions: 2.1.1-beta
            Reporter: Sandy Ryza
            Assignee: Sandy Ryza


It would be helpful to have a page that explains some of the non-obvious concepts used in
YARN scheduling.  We get a lot of questions about these on the user lists because they aren't
really documented anywhere.

An incomplete list of concepts to cover:
* Resources (memory / CPU)
* Reservations
* ResourceRequest format
* Disabling locality relaxation
