Creating the basic Parameter Contexts

Follow these steps to set up your individual Parameter Contexts and add the relevant parameters to them.

Create a Parameter Context for the common Kafka settings:
1. Select Parameter Contexts from the top-right Global menu in the NiFi UI.
  The NiFi Parameter Contexts dialog opens.
2. Click the (+) button in the top-right corner of the NiFi Parameter Contexts dialog to add a new Parameter Context.
3. Add a name for your Parameter Context on the SETTINGS tab.
  In this example the name is Kafka.
4. Switch to the PARAMETERS tab.
5. Click the (+) button to add the parameters you need for configuring your data flow.
6. Provide a name and a value in the Add Parameter dialog. You can also add a description of the parameter, if you want to.
  In this example, the following parameters are added:
  - Name: Kafka Brokers / Value: localhost:9092
  - Name: Kafka Group ID / Value: MyGroup
7. Click APPLY to save the Parameter Context.

Create the remaining Parameter Contexts by repeating sub-steps a to g of Step 1. Use the following names and values:


Parameter Context	Parameter Name	Parameter Value
GCP Cloud Storage	GCP Project ID	my-project
GCP Cloud Storage	GCP Bucket	my-bucket
S3	S3 Bucket	my-bucket
S3	S3 Region	us-west-2
Site Properties	Site Identifier	1234
Site Properties	Site Data Manager	MyDM
Source ABC	Kafka Topic	source-abc-topic
Source DEF	Kafka Topic	source-def-topic

You are ready with the individual Parameter Contexts that you will use to create your inheritance hierarchy. Your Parameter Contexts should look like this:
