    • Default value for 'yarn.scheduler.maximum-allocation-vcores' changed from 32 to 4.

    Description

      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?
