Subject [jira] [Created] (YARN-2824) Capacity of labels should be zero by default
Date Thu, 06 Nov 2014 21:54:35 GMT
Wangda Tan created YARN-2824:

             Summary: Capacity of labels should be zero by default
                 Key: YARN-2824
                 URL: https://issues.apache.org/jira/browse/YARN-2824
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: resourcemanager
            Reporter: Wangda Tan
            Assignee: Wangda Tan
            Priority: Critical

In existing Capacity Scheduler behavior, if user doesn't specify capacity of label, queue
initialization will be failed. That will cause queue refreshment failed when add a new label
to node labels collection and doesn't modify capacity-scheduler.xml.

With this patch, capacity of labels should be explicitly set if user want to use it. If user
doesn't set capacity of some labels, we will treat such labels are unused labels.
