> In order to enable HA (automatic failover) i had to set the following configs
> {code}
> <property>
>     <name>yarn.resourcemanager.ha.enabled</name>
>     <value>true</value>
>   </property>
>   
>   <property>
>     <name>yarn.resourcemanager.ha.automatic-failover.enabled</name>
>     <value>true</value>
>   </property>
>   <property>
>     <name>yarn.resourcemanager.ha.automatic-failover.embedded</name>
>     <value>true</value>
>   </property>
> {code}
> I believe the user should just have to set yarn.resourcemanager.ha.enabled=true and the
rest should be set as defaults. Basically automatic failover should be the default.
