> HFTP traffic served by DataNode shouldn't use service port on NameNode

> Key: HDFS-1357
> URL: https://issues.apache.org/jira/browse/HDFS-1357
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: data-node, security
> Reporter: Kan Zhang
> Assignee: Kan Zhang
> Attachments: h1357-01.patch, h1357-02.patch
>
>
> 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.
