NOTE

The Apache HDFS connector is in beta. See the Sources overview for more information on using beta-labeled connectors.

A base connection represents the authenticated connection between a source and Adobe Experience Platform.

This tutorial walks you through the steps to create a base connection for Apache Hadoop Distributed File System (hereinafter referred to as “HDFS”) using the Flow Service API.

Getting started

This guide requires a working understanding of the following components of Adobe Experience Platform:

Sources: Experience Platform allows data to be ingested from various sources while providing you with the ability to structure, label, and enhance incoming data using Platform services.
Sandboxes: Experience Platform provides virtual sandboxes which partition a single Platform instance into separate virtual environments to help develop and evolve digital experience applications.

The following sections provide additional information that you will need to know in order to successfully connect to HDFS using the Flow Service API.

Gather required credentials

Credential

Description

url

The URL defines auth params required for connecting to HDFS anonymously. For more information on how to obtain this value, refer to this HDFS document.

connectionSpec.id

The connection specification returns a source’s connector properties, including authentication specifications related to creating the base and source connections. The connection specification ID for AdWords is: 54e221aa-d342-4707-bcff-7a4bceef0001.

Using Platform APIs

For information on how to successfully make calls to Platform APIs, see the guide on getting started with Platform APIs.

Create a base connection

A base connection retains information between your source and Platform, including your source’s authentication credentials, the current state of the connection, and your unique base connection ID. The base connection ID allows you to explore and navigate files from within your source and identify the specific items that you want to ingest, including information regarding their data types and formats.

To create a base connection ID, make a POST request to the /connections endpoint while providing your HDFS authentication credentials as part of the request parameters.

API format

POST /connections

Request

The following request creates a base connection for HDFS:

curl -X POST \
    'https://platform.adobe.io/data/foundation/flowservice/connections' \
    -H 'Authorization: Bearer {ACCESS_TOKEN}' \
    -H 'x-api-key: {API_KEY}' \
    -H 'x-gw-ims-org-id: {ORG_ID}' \
    -H 'x-sandbox-name: {SANDBOX_NAME}' \
    -H 'Content-Type: application/json' \
    -d '{
        "name": "HDFS test connection",
        "description": "A test connection for an HDFS source",
        "auth": {
            "specName": "Anonymous Authentication",
            "params": {
                "url": "{URL}"
                }
        },
        "connectionSpec": {
            "id": "54e221aa-d342-4707-bcff-7a4bceef0001",
            "version": "1.0"
        }
    }'

Property

Description

auth.params.url

The URL that defines auth params required for connecting to HDFS anonymously

connectionSpec.id

The HDFS connection specification ID: 54e221aa-d342-4707-bcff-7a4bceef0001.

Response

A successful response returns details of the newly created connection, including its unique identifier (id). This ID is required to explore your data in the next tutorial.

{
    "id": "6a6a880a-2b15-4051-aa88-0a2b1570516d",
    "etag": "\"1801bb7d-0000-0200-0000-5ed6ad580000\""
}

Next steps

By following this tutorial, you have created an HDFS connection using the Flow Service API and have obtained the connection’s unique ID value. You can use this ID in the next tutorial as you learn how to explore a third-party cloud storage using the Flow Service API.
