      Some improvement requests from Yoram:

      1. directory browsing: the size, replication and block size fields are unused, and indeed the replication field contains random junk. It would be useful to use these fields to represent the size of the folder (recursive, like du -s), and possibly the number of files in the folder.

      2. since file sizes are typically very large, introducing a comma thousands separator will make them more readable.

      3. For a particular file I have the list of blocks that make it up. It would be useful to see the block placement information - which datanodes are holding that block. That's arguably more relevant than the block contents when clicking on the block.

      4. a nit - 2048 may be too small a chunk size by default. The overhead of getting the first byte is so high (redirect, connect, handshake etc.) that you may as well get 10-20k as your first shot.
