stanley shi updated HDFS-6049:
------------------------------
Affects Version/s: 2.0.5-alpha
> 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: 2.0.5-alpha, 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=192.168.2.201:8020";;
> 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=192.168.2.201:8020";,
> 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.
