Manuel Meßner commented on MAPREDUCE-5938:
------------------------------------------

"internal" and "external" interfaces. You really want your services to bind to
the internal interfaces, if you have to pay for any traffic on the external
interface.
> Shuffle port in nodemanager is binding to all IPs
