Description

Right now the MiniDFS builder is somewhat inflexible - it just takes a "numNameNodes" parameter, which is used to specify federated nameservices. In order to add HA support, we need to be able to be more specific when configuring the NNs – eg to test the case where there is one nameservice that is HA and another which is not.
