Subject [jira] [Commented] (HDFS-4471) Namenode WebUI file browsing does not work with wildcard addresses configured
Date Fri, 08 Feb 2013 00:27:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13574102#comment-13574102

Andrew Wang commented on HDFS-4471:
-----------------------------------

To finish this off, tested via configuring a wildcard address and browsing the filesystem
via the NN web UI (which worked successfully).

> 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.
