> The method {{Command#getNodeList}} in DiskBalancer was added in HDFS-9545, but it's never
used. We can improve that in the following aspects:
> 1.Change {{private}} to {{protected}} so that the subclass can use that method in the
> 2.Reuse the method {{Command#getNodeList}} and to construct a new method
> like this {{List<DiskBalancerDataNode> getNodes(String listArg)}}. This method
can be used for getting multiple nodes in the future. For example, if we want to use {{hdfs
diskbalancer -report -node}} or {{hdfs diskbalancer -plan}} with multiple specified nodes,
that method can be used.
