Subject [jira] [Created] (YARN-3823) Fix mismatch in default values for yarn.scheduler.maximum-allocation-vcores property
Date Thu, 18 Jun 2015 05:03:00 GMT
Ray Chiang created YARN-3823:
--------------------------------

             Summary: Fix mismatch in default values for yarn.scheduler.maximum-allocation-vcores
property
                 Key: YARN-3823
                 URL: https://issues.apache.org/jira/browse/YARN-3823
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.7.0
            Reporter: Ray Chiang
            Assignee: Ray Chiang
            Priority: Minor


In yarn-default.xml, the property is defined as:

  XML Property: yarn.scheduler.maximum-allocation-vcores
  XML Value: 32

In YarnConfiguration.java the corresponding member variable is defined as:

  Config Name: DEFAULT_RM_SCHEDULER_MAXIMUM_ALLOCATION_VCORES
  Config Value: 4

The Config value comes from YARN-193 and the default xml property comes from YARN-2. Should
we keep it this way or should one of the values get updated?
