-------------------------------------------

             Summary: TestContainerAllocation.testUserLimitAllocationMultipleContainers failure
after YARN-8896
                 Key: YARN-8944
                 URL: https://issues.apache.org/jira/browse/YARN-8944
             Project: Hadoop YARN
          Issue Type: Test
          Components: capacity scheduler
    Affects Versions: 3.3.0
            Reporter: Wilfred Spiegelenburg
            Assignee: Wilfred Spiegelenburg


YARN-8896 changes the behaviour of the CapacityScheduler by limiting the number of containers
that can be allocated in one heartbeat. It is an undocumented change in behaviour.

The change breaks the junit test: {{TestContainerAllocation.testUserLimitAllocationMultipleContainers}}

The maximum number of containers that gets assigned via the on heartbeat is 100 and it expects
199 to be assigned.
