System maintenance mode

Dell Data Processing Engine (DDPE) supports system maintenance mode. System maintenance mode allows administrators to safely upgrade Spark by preventing new job submissions.

Note

Activating and deactivating system maintenance mode requires the Spark system MANAGE privilege.

In the UI

You can activate system maintenance mode in the job submission UI by opening the options menu and selecting Activate maintenance mode:

Note

You cannot submit new jobs while maintenance mode is active.

You can deactivate system maintenance mode by selecting Deactivate maintenance mode from the same menu.

In the CLI

Use the system-maintenance admin commands to manage maintenance mode from the CLI.

For example, to:

check the current maintenance mode status:

./dell-data-processing-engine admin system-maintenance get

activate maintenance mode:

./dell-data-processing-engine admin system-maintenance enable

deactivate maintenance mode:

./dell-data-processing-engine admin system-maintenance disable

view the history of past maintenance mode activations:

./dell-data-processing-engine admin system-maintenance history
