Description

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: /
