  • Running time: The running time of the cluster.

  • Log activation: Determines whether the log saving function is activated.

  • Log position: If the log saving function is activated, the position where the log is saved is displayed here.

  • Software configuration: Information about software configuration.

  • Bootstrap/software configuration: Whether abnormalities occur.

  • High availability cluster: Whether the high availability cluster is activated.

Bootstrap action

The names, paths, and parameters of all configured bootstrap actions are listed here.

Software information

  • Main version: Use the main version of E-MapReduce.

  • Cluster type: The selected cluster type.
