             Summary: Set better defaults for HA configs
                 Key: YARN-1665
                 URL: https://issues.apache.org/jira/browse/YARN-1665
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: resourcemanager
            Reporter: Arpit Gupta


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.
