---------------------------------------------------------------

Thanks for reporting the breakage folks, and I apologize for the regression.

[~daryn], [~shahrs87], IIUC you would like to retain the option to disable the service RPC
port. In what situation do you see the extra RPC endpoint as disadvantageous?

bq. It should be: "A separate NameNode service RPC port is mandatory".
No, the goal is to make the NameNode always listen on a service RPC port by default even if
it is not enabled explicitly.

to be explicitly enabled by an administrator.
