1* Use of 100-CONTINUE for create & append, it seems not all client HTTP
libraries handle this (JDK HttpURLConnection to start). Plus the servlet API
does not provide support for it, it seems some servlet containers handle it but
in a way that it is non-standard (http://jira.codehaus.org/browse/JETTY-341) or
in a way that it never reaches the servlet
(http://stackoverflow.com/questions/848378/sending-100-continue-using-java-servlet-api).
Because of this I'm inclined to use a handle request as shown in the attached
API doc.

What i did for testing is i made the PUT call and did not send the data as i
was expecting a redirect. On the response i would capture the location header
and then send another put request with the data to the new location. That way i
did not have to wait for the 100 continue and be redirected.

> 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).
