Subject [jira] [Commented] (HDFS-4471) Namenode WebUI file browsing does not work with wildcard addresses configured
Date Thu, 07 Feb 2013 19:35:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13573835#comment-13573835

Aaron T. Myers commented on HDFS-4471:
--------------------------------------

Hey Daryn, I think you make a good point. I think the best fix would probably be to not pass
an address at all from the NN to the DN, but instead just pass the NN's nameservice ID and
have the DN look up in its own configs what address(es) to connect to. This would be a somewhat
more involved change, though.

How about this - given that the proper fix is more involved, and fixing this issue this way
will fix the web UI for many (most?) users, how about we commit this as-is and file a follow-up
JIRA to fix this properly at a later date. Does this sound OK by you?

> The namenode web UI currently passes around the NN's configured RPC address in the URL.
One of the places this is used is for file browsing; the NN redirects to a random DN, and
the DN then uses the NN address from the URL to contact the NN. However, this fails when the
NN RPC address is configured to be the wildcard (0.0.0.0).
> The fix is the same as in HDFS-3932: pass the configured address through {{NetUtils#getConnectAddress}}
first.
