Hmm, this message raises the question of "is the API available at all in
the client interfaces in old YARN versions"? I see `getNodeReports` exists in
the branch-2.2 branch, so when would you get into this particular situation?
Also, should probably log the exception. More things can go wrong here than
just what the message says.
