How about making the file path a part of the URL path? Also, why not drop the .jsp as it doesn't add anything. So:

{{http://<nn>:<port>/ls/path[<?option>[&option]*]}}

How does filter work - can you give an example, please?

For the response, I would strongly recommend using ISO 8601 for the timestamp representation. E.g.:

{{modified="yyyy-MM-ddThh:mm:ssZ"}}

> 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}
