Carlo Curino commented on YARN-4525:
------------------------------------
It is hard to construct a simple test (it depends on various subMaps
invocations I guess). But as part of YARN-5164 I am have a test
{{TestCapacityOvertimePolicy.testFailAvgBySum()}} that positively triggers this
bug.
> Bug in RLESparseResourceAllocation.getRangeOverlapping(...)

> One of our tests detected a corner case in getRangeOverlapping: When the
> RLESparseResourceAllocation object is a result of a merge operation, the
> underlying map is a "view" within some range. If 'end' is outside that
> range, headMap(..) throws an uncaught exception.
