Role Command Order

Role is another name for component (Ex: NAMENODE, DATANODE, RESOURCEMANAGER, HBASE_MASTER, etc.)

As the name implies, it is possible to tell Ambari about any order in which commands should be run for the components defined in your stack.
For example: "ZooKeeper Server should be started before starting NameNode". Or "HBase Master should be started only after NameNode and DataNodes are started".

This can be specified by including the role_command_order.json file in the stack-version folder.
