> NameNodeMXBean, NameNodeStatusMXBean, DataNodeMXBean are annotated {{@Public}} and {{@Stable}},
but some methods are being added. For example, DataNodeMXBean.getBPServiceActorInfo was added
between branch-2.7.3 and branch-2.8. Adding methods to interfaces breaks the user classes
which implement them, so we should make them {{@Private}}.
