Issue
Default Hadoop/Yarn installation has no security and can be used nefariously if left in that state
Suggested Fix
I don't really understand Hadoop - thus why I used your lovely guide - but at least mentioning that leaving Hadoop exposed to the public Internet is a problem would have been helpful to me. I would never have expected that it had an enabled-by-default public-facing command interface, much less that it is completely unsecured!

Research direction
Open the linked Hadoop cluster guide and locate the installation or configuration section that leaves the command interface exposed. Add a clear warning that an unsecured Hadoop/YARN installation should not be reachable from the public Internet, then verify the guide renders correctly and the warning appears near the relevant setup steps.
