Subject [jira] [Commented] (HDFS-13248) RBF: Namenode need to choose block location for the client
Date Wed, 19 Sep 2018 11:57:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-13248?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16620495#comment-16620495

Fei Hui commented on HDFS-13248:
--------------------------------

[~elgoiri] Before resolving this issue, i think it's meaningful that namenode log the real
client ip in callercontext. Should we file a new JARA to do this?

> When execute a put operation via router, the NameNode will choose block location for
the router, not for the real client. This will affect the file's locality.
> I think on both NameNode and Router, we should add a new addBlock method, or add a parameter
for the current addBlock method, to pass the real client information.
