-----------------------------------
Summary: Ozone: Support optional documentation link in KSM/SCM
webui
Key: HDFS-12661
URL: https://issues.apache.org/jira/browse/HDFS-12661
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ozone
Affects Versions: HDFS-7240
Reporter: Elek, Marton
Assignee: Elek, Marton
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.
