100 Continue issue, the problem I see with Arpit's solution is that if somebody 
is creating/appending an empty stream it will go into an infinite loop because 
the server will not see any content and it will respond with a 307 & Location 
over and over. IMO we need a getCreateHandle & getAppendHandle calls.

I am not quite sure why one would go to an infinite loop. When i make the 
initial call i do not send data and get the expected 307 and make the put call 
to the datanode with the data. Regardless i tested the case where on the 
redirect i sent empty content and webhdfs was able to create an empty file 
without any issues.

> 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).
