Subject [jira] [Commented] (HADOOP-14073) Document default HttpServer2 servlets
Date Tue, 21 Feb 2017 05:09:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14073?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15875375#comment-15875375

Yuanbo Liu commented on HADOOP-14073:
-------------------------------------

[~jzhuge]
{{/logs}} requires authorization to access while {{/jmx}} and {{/conf}} don't by default in
{{HttpServer2.java}}. I think if kms inherits {{HttpServer2.java}} or take advantage of it,
the access behaviors in hdfs,yarn and kms should be consistent.

It's would be great if you provide some steps/test cases to reproduce the defect that {{/logs}}
doesn't have access control in HADOOP-14060. If the defect exists, we should take care of
it.

> Since many components (NN Web UI, YARN RM/JH, KMS, HttpFS, etc) now use HttpServer2 which
provides default servlets /conf, /jmx, /logLevel, /stacks, /logs, and /static, it'd nice to
have an independent markdown doc to describe authentication and authorization of these servlets.
The docs for the related components can just link to this markdown doc.
> Good summary of HTTP servlets by [~yuanbo] for HADOOP-13119: https://issues.apache.org/jira/browse/HADOOP-13119?focusedCommentId=15635132&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15635132.
> I also made a poor attempt in https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-kms/src/site/markdown/index.md.vm#L1086-L1129
and https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs-httpfs/src/site/markdown/ServerSetup.md.vm#L153-L197.
