Description

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.
