> The CLI MiniCluster, {{MiniHadoopClusterManager}}, says that by default it
> does not format its directories, and provides the {{-format}} option to
> specify that it should do so. However, it builds its {{MiniDFSCluster}} like:
> {code}
> dfs = new MiniDFSCluster.Builder(conf).nameNodePort(nnPort)
> .nameNodeHttpPort(nnHttpPort).numDataNodes(numDataNodes)
> .startupOption(dfsOpts).build();
> {code}
> {{MiniDFSCluster.Builder}}, by default, sets {{format}} to true, so even
> though the {{startupOption}} is {{REGULAR}}, it will still format regardless
> of whether or not the flag is supplied.
