zhangduo commented on HDFS-8377:
--------------------------------

So let me open a new issue to abstract an application layer in the original 
WebHdfs implementation first.

For http/https, we could disable HTTP by default when shipping if we really 
care about security issues. HTTP/2 still contains a cleartext upgrading 
protocol means IETF members do not think it is the right time to force all 
flows running on ssl(They include this even when lots of browsers have put out 
statements that they will not support HTTP/2 without ssl). And it is very easy 
to implement, netty does most of the things.

For ALPN support, I think we could support both? And supporting openssl has 
much more work to do then supporting jetty-alpn I'd say... Maybe another issue.

Thanks.
