> 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.
