Alejandro Abdelnur commented on HDFS-2178:
------------------------------------------
Thanks for reviewing the patch Eli,
Regarding the 'pure proxy' question, as I've told Sanjay offline doing so it
would limit Hoop to be a proxy for webhdfs. As it is today is a proxy to any
Hadoop FileSystem implementation. In addition, if you want a pure http proxy,
you should use and off the shelf HTTP proxy, no need for a gateway.
Regarding webhdfs/httpfs interop, the TestWebhdfsFileSystem test does exactly
this.
Regarding config keys, I was keeping things as isolated as possible from the
rest of HDFS until Webhdfs & Hoop share the codebase.
Regarding a code sharing JIRA, as soon as this JIRA goes in.
All the other comments, I'll integrate them in a follow up patch.
Thanks again.

> We'd like to contribute Hoop to Hadoop HDFS as a replacement (an improvement)
> for HDFS Proxy.
> Hoop provides access to all Hadoop Distributed File System (HDFS) operations
> (read and write) over HTTP/S.
> The Hoop server component is a REST HTTP gateway to HDFS supporting all file
> system operations. It can be accessed using standard HTTP tools (i.e. curl
> and wget), HTTP libraries from different programing languages (i.e. Perl,
> Java Script) as well as using the Hoop client. The Hoop server component is a
> standard Java web-application and it has been implemented using Jersey
> (JAX-RS).
> The Hoop client component is an implementation of Hadoop FileSystem client
> that allows using the familiar Hadoop filesystem API to access HDFS data
> through a Hoop server.

> Hoop is a Maven based project that depends on Hadoop HDFS and Alfredo (for
> Kerberos HTTP SPNEGO authentication).
> To make the integration easy, HDFS Mavenization (HDFS-2096) would have to be
> done first, as well as the Alfredo contribution (HADOOP-7119).
