Description

This issue will track the design and implementation of (the first pass of) a servlet on the namenode for querying its filesystem via HTTP. The proposed syntax for queries and responses is as follows.

Query

GET http://<nn>:<port>/ls.jsp[<?option>[&option]*] HTTP/1.1

Where option may be any of the following query parameters:
path : String (default: '/')
recursive : boolean (default: false)
filter : String (default: none)

Response
The response will be returned as an XML document in the following format:

<listing path="..." recursive="(yes|no)" filter="..."
         time="yyyy-MM-dd hh:mm:ss UTC" version="...">
  <directory path="..."/>
  <file path="..." modified="yyyy-MM-dd hh:mm:ss" blocksize="..."
        replication="..." size="..."
        dnurl="http://dn:port/streamFile?..."/>
</listing>
