Cloudera Manager Admin Console Home Page

When you start the Cloudera Manager Admin Console, the Home > Status tab displays. You can also go to the Home > Status tab by clicking the Cloudera Manager logo in the top navigation bar.

The Status tab has two potential views: Table View and Classic View. The Classic View contains a set of charts for the selected cluster, while the Table View separates regular clusters, compute clusters, and other services into summary tables. You can use the Switch to Table View and Switch to Classic View links on each view to switch between the two views. Cloudera Manager remembers which view you select and remains in that view.
