Starting services and components

After starting a test session, you may need to start services and NiFi components on the canvas before your draft flow can actually start processing data.

Make sure that you have DFDeveloper permission to perform this task. For information on account and resource roles, see Cloudera Data Flow Authorization.
You have started a test session in Flow Designer.

Click Flow Options > Services to enable Services.
Select a service you want to enable, then click Enable.
Repeat this step for all Services.
tip
You can also select Enable Service and Referencing Components. It will not only enable the controller service, but also any component that references it. This way, you do not need to enable the components separately.
Click Flow Design in the breadcrumbs on top of the page to return to the canvas.
Start all processors that are not running (you see a Stopped symbol next to the processor name) by selecting the processor on the canvas then clicking Start.

tip

You can also start every processor in the flow by selecting Start on the Process Group level.

The flow starts executing. On the Flow Design canvas you can observe statistics on your processors change as they consume data and execute their respective tasks. You can also observe one or more blue notification pills, providing information about the current task. Potential issues that need to be addressed are called out in an orange

notification pill on the individual processors.
