Description

Most of webhdfs's PUT operations have no message body. The HTTP/1.1 spec is fuzzy in how PUT requests with no body should be handled. If the request does not specify chunking or Content-Length, the server may consider the request to have no body. However, popular proxies such as Apache Traffic Server will reject PUT requests with no body unless Content-Length: 0 is specified.
