Resolving as fixed. Thanks, Kan! > 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 > Fix For: 0.22.0 > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
