> TestRegionAwareEnsemblePlacementPolicy#testNewEnsembleWithThreeRegions is failing because RegionAwareEnsemblePlacementPolicy is not working as expected.
> The current allocation policy is not evenly across the regions. The write quorum size is also not calculated correctly.
> We need  to fix the placement policy and then fix the the test case.
