Alejandro Abdelnur commented on HDFS-5703:
------------------------------------------
[~daryn], HttpFS is not a proxy, it is a gateway:
(client) ---[HTTP/S]---> (HttpFS, uses 'FileSystem impl' client) ---[impl
client/server protocol]---> ('FileSystem impl' server)
In the case of working against HDFS:
(client) ---[HTTP/S]---> (HttpFS, uses 'DFSFileSystem impl') ---[Hadoop
RPC]---> (HDFS)
HttpFS does not use any internal classes from HDFS, thus we have to create the
token WebHdfsFileSystem client expects.
> Add support for HTTPS and swebhdfs to HttpFS
