NameNode Schema for HttpFileSystem
----------------------------------

                 Key: HADOOP-1568
                 URL: https://issues.apache.org/jira/browse/HADOOP-1568
             Project: Hadoop
          Issue Type: New Feature
          Components: fs
            Reporter: Chris Douglas
            Assignee: Chris Douglas


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

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:
{noformat}
<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>
{noformat}
