Marco Nicosia updated HADOOP-5010:

Fix Version/s: 0.20.0
bq. Counting the listPaths servlet, there are already two interfaces for
browsing HDFS over HTTP, aren't there? This seems to be asking for a way to
manipulate HDFS without the Hadoop jar. If reading is sufficient, then the HFTP
servlets should suffice for hand-rolled tools
Reading is sufficient (from my original request). I didn't know that there's a
combination of HTTP requests which will allow an http client to get directory
listings and file data.
Does listPaths and the .../data/... component respect the dfs.web.ugi
directive? (But then, this is what HDFS proxy was invented for, so permissions
should be a non-issue.) When Hadoop becomes kerberized, these servlets need to
require credentials over HTTP.
bq. but they need to be documented.
Yes. Switching this bug to a documentation task.

> bq. The URI for this should be something like hftp://host:port/a/b/c, since,
> while HTTP will be used as the transport, this will not be a FileSystem for
> arbitrary HTTP urls.
> Recently, we've been talking about implementing an HDFS proxy (HADOOP-4575)
> which would be a secure way to make HFTP/HSFTP available. In so doing, we may
> even remove HFTP/HSFTP from being offered on the HDFS itself (that's another
> discussion).
> In the case of the HDFS proxy, does it make sense to do away with the
> artificial HFTP/HSFTP protocols, and instead simply offer standard HTTP and
> HTTPS? That would allow non-HDFS-specific clients, as well as using various
> standard HTTP infrastructure, such as load balancers, etc.
> NB, to the best of my knowledge, HFTP is only documented on the
> [distcp|http://hadoop.apache.org/core/docs/current/distcp.html] page, and
> HSFTP is not documented at all?
