Aaron T. Myers updated HDFS-1575:
---------------------------------

    Attachment: hdfs-1575-22.0.patch

What's attached is a faithful back-port of the trunk commit. In the course of doing this back-port I identified a bug, which I've filed under HDFS-1964. Let's commit this patch to branch-0.22 and then I'll back-port the bug fix.

> 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}}
