How to configure kerberos to access namenode's web jsp?
Hi, hadooper:
I configure kerberos in hdfs, when I access
http://hdpnn:50070/nn_browsedfscontent.jsp, I got the error like this:
HTTP ERROR 500
Problem accessing /nn_browsedfscontent.jsp. Reason:
Security enabled but user not authenticated by filter
Caused by:
java.io.IOException: Security enabled but user not authenticated by filter

Hi,
You will need to additionally follow this for getting back web UI
functionality on a secured cluster:
http://hadoop.apache.org/common/docs/stable/HttpAuthentication.html
Let us know if it helps!
