Automatic ResourceManager failover is enabled by default, so it must be disabled for manual failover.
To configure manual failover for ResourceManager HA, add the
yarn.resourcemanager.ha.automatic-failover.enabled
configuration property to the etc/hadoop/conf/yarn-site.xml
file,
and set its value to "false":
<property> <name>yarn.resourcemanager.ha.automatic-failover.enabled</name> <value>false</value> </property>
