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

Create and Append: 
The hdfs-proxy, does not need to redirect to a DN (there is no DN exposed). The 
proxy can serve the request itself. 
Only webhdfs (built into NN and DN) needs to redirect. There will be some 
differences between the 
proxy API and the webhdfs API. The proxy API can be a subset of the webhdfs 
API. Does that make sense.

> 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).
