> HDFS-599 introduced a new service port on NameNode to separate system traffic (e.g.,
heartbeats/blockreports) from client file access requests so that they can be prioritized.
 All Datanode traffic now goes to the service port. However, datanode also serves as a proxy
for HFTP requests from client (served by StreamFile servlet). These HFTP traffic should continue
to use the client port on NameNode. Moreover, using the service port for HFTP is incompatible
with the existing way of selecting delegation tokens.
