Description

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.
