Subject [jira] Created: (HDFS-1357) HFTP traffic served by DataNode shouldn't use service port on NameNode
Date Wed, 25 Aug 2010 21:56:19 GMT
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
            Reporter: Kan Zhang
            Assignee: Kan Zhang


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.
