Sanjay Radia commented on HDFS-2178:
------------------------------------

> ...backwards compatibility ...

You mean "compatibility" not "backward compatibility".
Are we trying to be backward compatible with Hftp and with HDfsProxy?


BTW some thing make sense for webhdfs but not for a proxy (like Hoop or hdfs proxy): redirection
to the data node holding the  data.

> 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).
