Subject What is the difference between HttpFS and WebHDFS?
Date Fri, 22 May 2015 04:12:51 GMT
It looks like that both all support almost same HTTP REST API.  
The HttpFS is a HTTP gateway, i.e, all client requests must access directly it. But WebHDFS
allows to directly access NameNode and DataNode, and a WebHDFS FileSystem URI has the format
'webhdfs://<HOST>:<HTTP_PORT>/<PATH>', what is the HOST and HTTP_PORT? 
BTW, if use HttpFS to act as proxy on WebHDFS, i know how to indicate the HOST and PORT, but
if only use WebHDFS without HttpFS proxy, i don't know how to use.
