>             Project: Hadoop YARN
>          Issue Type: Sub-task
>          Components: documentation, resourcemanager
>            Reporter: Wangda Tan
>            Assignee: Masatake Iwasaki
>            Priority: Minor
>             Fix For: 2.7.0
>         Attachments: YARN-2807.1.patch, YARN-2807.2.patch, YARN-2807.3.patch, YARN-2807.4.patch
> Currently the help message of "yarn rmadmin -transitionToActive" is:
> {code}
> transitionToActive: incorrect number of arguments
> Usage: HAAdmin [-transitionToActive <serviceId> [--forceactive]]
> {code}
> But the --forceactive not works as expected. When transition RM state with --forceactive:
> {code}
> yarn rmadmin -transitionToActive rm2 --forceactive
> Automatic failover is enabled for org.apache.hadoop.yarn.client.RMHAServiceTarget@64c9f31e
> Refusing to manually manage HA state, since it may cause
> a split-brain scenario or other incorrect state.
> If you are very sure you know what you are doing, please
> specify the forcemanual flag.
> {code}
> As shown above, we still cannot transitionToActive when automatic failover is enabled
with --forceactive.
> The option can work is: {{--forcemanual}}, there's no place in usage describes this option.
I think we should fix this
