Subject [jira] [Created] (YARN-302) Fair scheduler assignmultiple should default to false
Date Tue, 01 Jan 2013 21:28:12 GMT
Sandy Ryza created YARN-302:

             Summary: Fair scheduler assignmultiple should default to false
                 Key: YARN-302
                 URL: https://issues.apache.org/jira/browse/YARN-302
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager, scheduler
    Affects Versions: 2.0.2-alpha
            Reporter: Sandy Ryza
            Assignee: Sandy Ryza

The MR1 default was false.  When true, it results in overloading some machines with many tasks
and underutilizing others.
