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.
