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.
