-----------------------------------------
Hi, [~xyao]. I'm sorry for very late response. Thanks for your review and
comments. I uploaded a new patch based on your advice.
> Line 423: suggest adding a separate section and put the content(links) under
> it.
Done in the latest patch.
> This page is for HTTPFS. To avoid confusion, I would suggest we add a

> Swebhdfs document.
Since HttpFS provides WebHDFS interface, the clients of HttpFS follow WebHDFS
REST API. It is not different between "HttpFS over SSL" and "WebHDFS over SSL"
from the perspective of the clients. It might be a little redundant to add the
same {{ssl-client.xml}} example. The latest patch still uses the link but also
adds more sentence to avoid confusion. How does look that?
> Line 161: /etc/hadoop/hdfs-site.xml has a configuration key to enable secure
> http,
> i.e., dfs.http.policy=HTTPS_ONLY
> Also note that dfs.http.policy is not for swebhdfs only. This will also

> We also need to document settings for the server side settings, e.g.,
> ssl-server.xml.
{{dfs.http.policy=HTTPS_ONLY}} and {{ssl-server.xml}} are on the server side
settings and clients don't use it. Since {{Webhdfs.md}}(WebHDFS REST API) is
focusing on the client side, I think we should not write it in {{Webhdfs.md}}.
I agree to adding the documents for the server side settings. That seems to be
missing from the current community documents. How about doing it in HDFS-12736?
> Line 198: suggest give a full path: ssl-client.xml ->
> /etc/hadoop/ssl-client.xml
I tried some experiments and it seems that {{hadoop.ssl.client.conf}} reqires
only relative path, not absolute path. So
{{hadoop.ssl.client.conf=/etc/hadoop/ssl-client.xml}} doesn't work well. The
latest patch includes the explanation.
