Tsz Wo (Nicholas), SZE commented on HDFS-2316:
----------------------------------------------

> But the write/append handle thingy, any other option?

We probably should use "Expect: 100- continue" http header.  See 8.2.3 Use of the 100 (Continue)
Status in http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html#sec8.2

> We current have hftp for accessing HDFS over HTTP.  However, hftp is a read-only FileSystem
and does not provide "write" accesses.
> In HDFS-2284, we propose to have webhdfs for providing a complete FileSystem implementation
for accessing HDFS over HTTP.  The is the umbrella JIRA for the tasks.
