Viewing the Maintenance Mode Status of a Cluster
For any cluster, you can view the components (service, roles, or hosts) that are in maintenance mode.
- From the Cloudera Manager Home page, select the cluster that you want to view the maintenance mode status for.
- Click . This pops up a dialog box that shows the components in your cluster that are in maintenance mode, and indicates which are in effective maintenance mode as well as those that have been explicitly placed into maintenance mode.
From this dialog box you can select any of the components shown there and remove them from maintenance mode.
If individual services are in maintenance mode, you will see the maintenance mode icon next to the Actions button for that service.
