Jim Brennan commented on HDFS-14960:
------------------------------------
Thanks [~ayushtkn]! I will remove the precondition in
BlockPlacementPolicyWithNodeGroup and add some additional verification. Note
that with the changes I've made, one of the test cases
(testBalancerEndInNoMoveProgress) now achieves what we want. It fails if the
balancer does not use NetworkTopologyWithNodeGroup.
> TestBalancerWithNodeGroup should not succeed with DFSNetworkTopology

> As reported in HDFS-14958, TestBalancerWithNodeGroup was succeeding even
> though it was using DFSNetworkTopology instead of
> NetworkTopologyWithNodeGroup.
> [~inigoiri] rightly suggested that this indicates the test is not very good -
> it should fail when run without NetworkTopologyWithNodeGroup.
> We should improve this test.
