Learn how to collect the information you need to deploy the Azure Event Hub to ADLS ReadyFlow, and meet other prerequisites.
For your data ingest source
You have obtained the Event Hub Namespace and Instance name
- Navigate to msignite, in this example): and select your Event Hub instance (
Copy the namespace and the Event Hub Instance name (msignite/msignite in this example).
- You have created an Event Hub Shared Access Policy and obtained its name and
Primary Access Key
- Click Shared access policies.
- Set up a shared access policy that allows “Listen”. Copy the Policy name.

You have synchronized your user to the CDP Public Cloud environment that you enabled for DataFlow.
For information on how to synchronize your user to FreeIPA, see Performing User Sync.
- You have granted your CDP user the
DFCatalogAdmin and DFFlowAdmin roles to
enable your user to add the ReadyFlow to the Catalog and deploy the flow definition.

For your data ingest target
You have your ADLS container and path into which you want to ingest data.
- You have performed one of the following to configure access to your ADLS folder:
You have configured access to the ADLS folders with a RAZ enabled environment.It is a best practice to enable RAZ to control access to your object store folders. This allows you to use your CDP credentials to access ADLS folders, increases auditability, and makes object store data ingest workflows portable across cloud providers.
- Ensure that Fine-grained access control is enabled for your DataFlow environment.
- From the Ranger UI, navigate to the ADLS repository.
- Create a policy to govern access to the ADLS container and path used in your ingest workflow. For example: adls-to-adls-avro-ingest
- Add the machine user that you have created for your ingest workflow to ingest the policy you just created.
You have configured access to ADLS folders using ID Broker mapping.If your environment is not RAZ-enabled, you can configure access to ADLS folders using ID Broker mapping.
- Access IDBroker mappings.
- To access IDBroker mappings in your environment, click .
- Choose the IDBroker Mappings tab where you can provide mappings for users or groups and click Edit.
- Add your CDP Workload User and the corresponding Azure role that provides write access to your folder in ADLS to the Current Mappings section by clicking the blue + sign.
- Click Save and Sync.
