Subject [jira] [Commented] (HDFS-3932) NameNode Web UI broken if the rpc-address is set to the wildcard
Date Fri, 21 Sep 2012 08:47:08 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13460358#comment-13460358
] 

Steve Loughran commented on HDFS-3932:
--------------------------------------

BTW, has anyone tested this on
# box w/ multiple addresses
# box with totally broken networking that returns null instead of a hostname/IP addr. One
of mine with a buggy resolv.conf had this. Such a box is beyond hope -the goal should just
be to bail out with a message saying "your network is broken", instead of a stack trace.

Networking is one area that has higher variance across installations than any other -and a
high variance in understanding, especially for people setting up pseudo clusters. Hadoop needs
to fail in a way that lets them know it's their problem, not the Hadoop codebase.

> If {{dfs.namenode.rpc-address}} is set to the wildcard some of links in the dfsnodelist.jsp
and browseDirectory.jsp pages are broken because the nnaddr field is passed verbatim (eg nnaddr=0.0.0.0:8021).
