How do I configure application-hadoop.yml if ha mode is not enabled in my hadoop test cluster

hadoop:
  # Configuration dependency for task-application & task-parser modules
  namenodes:
    - nameservices: logs-hdfs               # dfs.nameservices value
      namenodesAddr: [ "machine1.example.com", "machine2.example.com" ]   # dfs.namenode.rpc-address.[nameservice ID].[name node ID] value
      namenodes: ["nn1", "nn2"] # dfs.ha.namenodes.[nameservice ID] value

Has anyone tested it? I'd like to have an example
thank you!!!
