Ray Chiang commented on YARN-5665:
----------------------------------
You can drop the "Please" in the documentation. I'd suggest the phrasing:
{quote}
"Use the fully qualified class name, e.g."
{quote}
The term _qualified_ is defined in the "Names" section of the Java Language
Specification.
> Documentation does not mention package name requirement for
> yarn.resourcemanager.scheduler.class

> refers to FairScheduler, when it documents the setting
> yarn.resourcemanager.scheduler.class. What it forgets to mention is that the
> user has to specify the full class path like
> org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler
> otherwise the system throws java.lang.ClassNotFoundException: FairScheduler.
> It would be nice, if the documentation specified the full class path, so that
> the user does not need to look it up.
