Subject [jira] [Created] (HDFS-6049) Web UI: Browse file system from data node will fail with secured HDFS

stanley shi created HDFS-6049:

             Summary: Web UI: Browse file system from data node will fail with secured HDFS

                 Key: HDFS-6049
                 URL: https://issues.apache.org/jira/browse/HDFS-6049
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.2.0
            Reporter: stanley shi

On a secured HDFS, the webUI for the Active Namenode will display, but when you select a Live
Datanode, the browser displays an error and does not display datanode information. It does
list a link to "Logs" but when you click on that you get an unauthorized error message.

When user click on the "live nodes" link on the namenode webui, it goes to "dfsnodelist.jsp"
to show the list of datanodes;
on top half of the "dfsnodelist.jsp" page, you can choose to "browse the filesystem", which
direct user to the link "http://*:50070/nn_browsedfscontent.jsp", and this "nn_browsedfscontent.jsp"
will redirect user to a random datanode "http://:1006/browseDirectory.jsp?namenodeInfoPort=50070&dir=/&delegation=****&nnaddr=";
note here the "delegation" is added by namenode to the above link; so in this link, user can
browse the filesystem;
On the bottom half of the "dfsnodelist.jsp" page, a list of nodes are shown; when you click
on one data node, the page goes to "http://**:1006/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F&nnaddr=",
without the "delegation" part, so in this link, user will not be able to browse the content
of the filesystem, and an error message is shown.
