Allen Wittenauer commented on YARN-2345:
----------------------------------------

Essentially, yes.   For reference, here's the dfsadmin -report for a single node setup:

There's obviously some details missing from this simple setup (rack topology!). An analog
should report similar information as to what is available from the RM UI.
