Subject How to configure kerberos to access namenode's web jsp?
Date Thu, 14 Jun 2012 10:46:17 GMT
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
