>    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?
