[jira] [Commented] (HDFS-12564) Add the documents of swebhdfs configurations on the client side

["Xiaoyu Yao (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDFS-12564?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16234398#comment-16234398 ] 

Xiaoyu Yao commented on HDFS-12564:
-----------------------------------

Thanks [~tasanuma0829]. The patch looks good to me overall, here are a few comments:

Distcp.md.vm

Line 423: suggest adding a separate section and put the content(links) under it.

"#H3 Secure Copy over the wire with distcp"


ServerSetup.md.vm

This page is for HTTPFS. To avoid confusion, I would suggest we add a detailed ssl-client.xml example instead of linking it to 
Swebhdfs document. 


Webhdfs.md

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 affect all the HTTP endpoints of HDFS such as the NN, DN WebUI, JMX, QJM.
Line 198: suggest give a full path: ssl-client.xml -> /etc/hadoop/ssl-client.xml 


We also need to document settings for the server side settings, e.g., ssl-server.xml.

> Documentation does not cover the swebhdfs configurations on the client side. We can reuse the hftp/hsftp documents which was removed from Hadoop-3.0 in HDFS-5570, HDFS-9640.
