             Summary: Validate that the duration of the periodic reservation is 
less than the periodicity
                 Key: YARN-6687
                 URL: https://issues.apache.org/jira/browse/YARN-6687
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: reservation system
            Reporter: Subru Krishnan
            Assignee: Subru Krishnan


Duration of a reservation (endTime - startTime) is specified independently of 
the recurrence. This can lead to requests where the duration exceeds the 
periodicity, for e.g: an hourly reservation that runs for 2 hours. This will 
result in multiple concurrently active instances for the same reservation which 
is hard both to manage as well as grok. This jira proposes to reject such 
requests by clearly informing the user.
