Sandy Ryza created YARN-664:
-------------------------------
Summary: throw InvalidRequestException for requests with different
capabilities at the same priority
Key: YARN-664
URL: https://issues.apache.org/jira/browse/YARN-664
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager, scheduler
Affects Versions: 2.0.4-alpha
Reporter: Sandy Ryza
Assignee: Sandy Ryza
Nothing stops an application from submitting a request with priority=1,
location=*, memory=1024 and a request with priority=1, location=rack1,
memory=1024. However, this does not make sense under the request model and can
cause bad things to happen in the scheduler. It should be possible to detect
this at AMRM heartbeat time and throw an exception.
