Connect to Hadoop Distributed File System

Learn to create a connection to an Hadoop Distributed File System to use as a target in an OCI GoldenGate replication process.

Before you begin

Ensure that you:

• Review how OCI GoldenGate connects to your source and targets.

• Configure the required policies to enable secure Vault and Secrets access, such as use secrets, use vaults, and read secret-bundles. For more information, see Minimum recommended policies.

Create the connection

To create an Hadoop Distributed File System connection:

1. From the OCI GoldenGate Overview page, select Connections.

   You can also select Create Connection under the Get started section and skip to step 3.

2. On the Connections page, select Create Connection.

3. On the Create Connection page, complete the fields as follows:

   1. For Name, enter a name for the connection.

   2. (Optional) For Description, enter a description that helps you distinguish this connection from others.

   3. (For GoldenGate on Multicloud only) Select your Subscription, and then complete the following fields.

      1. From the Compartment dropdown, select the compartment in which the Resource Anchor resides.

      2. Select the Multicloud partner region.

      3. Select your Partner availability zone. The available options populate based on the selected Multicloud partner region.

   4. For Compartment, select the compartment in which to create the connection.

   5. For Type, select Hadoop Distributed File System.

   6. Drop or select an XML configuration file for this database for Hadoop configuration file.

   7. Expand Show advanced options. You can configure the following options:

      • Security

        • Deselect Use vault secrets you prefer not to use password secrets for this connection. If not selected:

          • Select Use Oracle-managed encryption key to leave all encryption key management to Oracle.

          • Select Use customer-managed encryption key to select a specific encryption key stored in your OCI Vault to encrypt your connection credentials.

      • Network connectivity

        • Shared endpoint, to share an endpoint with the assigned deployment. You must allow connectivity from the deployment's ingress IP.

        • Dedicated endpoint, for network traffic through a dedicated endpoint in the assigned subnet in your VCN. You must allow connectivity from this connection's ingress IPs.

          Note:

          • If a dedicated connection remains unassigned for seven days, then the service converts it to a shared connection.
          • Learn more about Oracle GoldenGate connectivity.

      • Security attributes: Add security attributes to control access to this connection using Zero Trust Packet Routing (ZPR).

      • Tags: Add tags to organize your resources.

4. Select Create.

After the connection is created, it appears in the Connections list. Ensure that you assign the connection to a deployment to use it as a target in a replication.
