The Inventory Tree (Traversal Spec) feature in vROps allows you to easily navigate your Apache Hadoop environment. The hierarchical structure implicitly shows relationships among resources and enables quick drill-downs to root-cause issues.

To access your Apache Hadoop Inventory Tree, select Environment from the top navigation bar, then select Apache Hadoop from the left panel. Click on a resource from the Inventory Tree to populate details about the resource on the right.

Note: All Apache Hadoop resource icons (with the exception of Cluster) also have power state icons (Power On, Power On, Power Suspended) that are visible from the Inventory Tree view only. You can see an example of the Power On (green arrow) overlay on the ResourceManager, NameNode, and DataNode resources in the example Inventory Tree on the left.
