[jira] [Created] (YARN-721) ContainerManagerImpl failed to authorizeRequest

PengZhang created YARN-721:
------------------------------

             Summary: ContainerManagerImpl failed to authorizeRequest
                 Key: YARN-721
                 URL: https://issues.apache.org/jira/browse/YARN-721
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.0.3-alpha
            Reporter: PengZhang


When security is enabled, resource check will be failed. AM master cannot be launched.
It reports like "Expected resource <memory:1800, vCores:1> but found <memory:1536, vCores:1>"

I tracked this problem, and found it's imported in Yarn-2. In RMAppAttemptImpl.ScheduleTransition, after allocate(), scheduler normalized Resource and created a new Resource object. Resource objects in scheduler and RMAppAttemptImp are used for schedule and launch separately. The difference value met in ContainerManagerImpl, and caused this problem.
