Description

TestLeafQueue#testReservation fails intermittent

[ERROR] Tests run: 36, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 20.813 s <<< FAILURE! - in org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.TestLeafQueue
[ERROR] testReservation(org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.TestLeafQueue)  Time elapsed: 0.219 s  <<< ERROR!
org.mockito.exceptions.misusing.WrongTypeOfReturnValue: 

Integer cannot be returned by isMultiNodePlacementEnabled()
isMultiNodePlacementEnabled() should return boolean
***
If you're unsure why you're getting above error read on.
Due to the nature of the syntax above problem might occur because:
1. This exception *might* occur in wrongly written multi-threaded tests.
   Please refer to Mockito FAQ on limitations of concurrency testing.
2. A spy is stubbed using when(spy.foo()).then() syntax. It is safer to stub spies - 
   - with doReturn|Throw() family of methods. More in javadocs for Mockito.spy() method.
