--------------------------------
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.
