> When Kerberos authentication is enabled, we are unable to browse to the data nodes using ( Name node web page --> Live Nodes --> Select any of the data nodes). The reason behind this is the delegation token is not provided as part of the url in the method (generateNodeDataHeader method of NodeListJsp)
> {code}
>       String url = HttpConfig.getSchemePrefix() + d.getHostName() + ":"
>           + d.getInfoPort()
>           + "/browseDirectory.jsp?namenodeInfoPort=" + nnHttpPort + "&dir="
>           + URLEncoder.encode("/", "UTF-8")
>           + JspHelper.getUrlParam(JspHelper.NAMENODE_ADDRESS, nnaddr);
> {code}
> But browsing the file system using name node web page --> Browse the file system -> <any directory> is working fine as the redirectToRandomDataNode method of NamenodeJspHelper creates the delegation token
> {code}
>     redirectLocation = HttpConfig.getSchemePrefix() + fqdn + ":" + redirectPort
>         + "/browseDirectory.jsp?namenodeInfoPort="
>         + nn.getHttpAddress().getPort() + "&dir=/"
>         + (tokenString == null ? "" :
>            JspHelper.getDelegationTokenUrlParam(tokenString))
>         + JspHelper.getUrlParam(JspHelper.NAMENODE_ADDRESS, addr);
> {code}
> I will work on providing a patch for this issue.
