Subject [jira] [Updated] (YARN-664) throw InvalidRequestException for requests with different capabilities at the same priority
Date Tue, 14 May 2013 19:57:16 GMT

     [ https://issues.apache.org/jira/browse/YARN-664?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sandy Ryza updated YARN-664:
----------------------------

    Description: Nothing stops an application from submitting a request with priority=1, location=*,
memory=1024 and a request with priority=1, location=rack1, memory=2048.  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.  (was:
