> Key: HDFS-12661
> URL: https://issues.apache.org/jira/browse/HDFS-12661
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ozone

> In some cases it could be useful to include additional documentation to the
> SCM/KSM web ui.
> This patch includes an optional hook. During the startup scm/ksm web ui do a
> HTTP HEAD request and if docs/index.html exists, an additional Documentation
> link will be displayed in the menu header.
> Long term we can generate documentation automatically from the source.
> Testing:
> Do a full build, start scm: no link in the ui.
> Add some optional documentation (choose one):
> * hadoop-hdfs-project/hadoop-hdfs/src/main/webapps/scm/docs/index.html
> (before build)
> * hadoop-hdfs-project/hadoop-hdfs/target/webapps/scm/docs/index.html (after
> clean, before build)
> *
> hadoop-dist/target/hadoop-3.1.0-SNAPSHOT/share/hadoop/hdfs/webapps/scm/docs/index.html
> (after build)
> And start scm again. There should be a documentation link in the menu which
> opens the optional documentation.
