Is this test failing for you?

[iamhumanbeing]

@srowen : this test is not failing, but the test name is not correct. it should be "minNumPostShufflePartitions: 5", cause the unit test code set minNumPostShufflePartitions to 5, not 3.

determining the number of reducers: aggregate operator(minNumPostShufflePartitions: 3)
