Download a flow definition from NiFi

Before you can run an Apache NiFi flow in Cloudera DataFlow, you need to download the NiFi flow as a flow definition. The Download flow definition option in NiFi allows you to download the flow definition of a process group as a JSON file. The file can be imported into Cloudera DataFlow using the Import Flow Definition option.

Develop your data flow in NiFi.

Select the process group that you want to transfer to Cloudera DataFlow.
For recommendations on how to export your process groups for deployment in Cloudera DataFlow, see Best Practices for Flow Definition Development.
Right-click the process group.
Select Download flow definition.

note

You can download flow definitions from NiFi at any level of your process group hierarchy. If you download one particular process group, your package contains the flow(s) included in the selected process group. When you download your flow definition from the root canvas level, you basically export all your data flows running on a cluster in one package, as the root canvas is the top level in the process group hierarchy.

If you download a versioned process group, the versioning information is not included in the downloaded JSON file.

After the download, you can upload your flow to Cloudera DataFlow.

For more information on how to plan and organize your NiFi data flows, see Best Practices for Flow Definition Development.

The data flow is downloaded as a JSON file. You have a portable NiFi flow ready to be imported into Cloudera DataFlow.
