viewing block from web UI broken
--------------------------------

                 Key: HDFS-1575
                 URL: https://issues.apache.org/jira/browse/HDFS-1575
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 0.22.0
            Reporter: Todd Lipcon
            Priority: Blocker
             Fix For: 0.22.0


DatanodeJspHelper seems to expect the file path to be in the "path info" of the HttpRequest, rather than in a parameter. I see the following exception when visiting the URL {{http://localhost.localdomain:50075/browseBlock.jsp?blockId=5006108823351810567&blockSize=20&genstamp=1001&filename=%2Fuser%2Ftodd%2Fissue&datanodePort=50010&namenodeInfoPort=50070}}

java.io.FileNotFoundException: File does not exist: /
