Devaraj Das updated HADOOP-347:
-------------------------------
Attachment: fsnamesystem.patch
Fixed a problem whereby negative values of (randomly generated) array indices
were not checked. This is an incremental patch over what has already been
committed. Sorry for overlooking this.

> Implement HDFS content browsing interface over HTTP. Clients would connect to
> the NameNode and this would send a redirect to a random DataNode. The
> DataNode, via dfs client, would proxy to namenode for metadata browsing and
> to other datanodes for content. One can also view the local blocks on any
> DataNode. Head, Tail will be provided as shorthands for viewing the first
> block and the last block of a file.
> For full file viewing, the data displayed per HTTP request will be a block
> with a PREV/NEXT link. The block size for viewing can be a configurable
> parameter (the user sets it via the web browser) to the HTTP server (e.g.,
> 256 KB can be the default block size for viewing files).
