RE: Issue when clicking on BrowseFileSystem
Andy,

:)
You are absolutely right.  It was inded  "localhost..:"   in the URL. When I changed it to my IP address the page duly loaded. Which .xml file is responsible for this setting?

Cheers,
Andy

Andy,

It sounds like your namenode thinks the datanode is on localhost. The "browse the filesystem" URL gets its IP address from the DN registration message. Is the URL that throws dns_unresolved_hostname the nn_browsedfscontent.jsp URL, or the browseDirectory.jsp that it redirects to?

What's your dfs.namenode.rpc-address and http-address settings? Are there any odd entries in /etc/hosts like having your hostname listed on a 127.0.0.1 line?  Is this on a single-node cluster or a multi-node cluster?

If none of the above seems diagnostic, what does the
"NameSystem.registerDatanode: node registration from DatanodeRegistration(192.168.122.87" log messages in your namenode log look like?
