Defining co-located Kafka clusters using Kafka credentials

Before you can start replicating data with Streams Replication Manager, you must define the co-located Kafka clusters that take part in the replication process. This can be done using Cloudera Manager by creating Kafka credentials.

The following list of steps walk you through how you can define the co-located Kafka cluster using Kafka credentials.

  1. In Cloudera Manager, go to Administration > > External Accounts.
  2. Go to the Kafka Credentials tab.

    The Kafka Credentials tab enables you to create, configure, and manage Kafka credentials. On this tab you will create a credential for your co-located Kafka cluster.

  3. Create and configure Kafka credentials for the external clusters:
    1. Click Add Kafka credentials.
    2. Configure the Kafka credential:
      The security configuration of the co-located cluster determines which of the available properties you must set. To see which exact properties are required for your scenario, click one of the following tabs matching the security protocol of the cluster you are defining:
      • Name
      • Bootstrap servers
      • Security protocol
    3. Click Add.
      If credential creation is successful, a new entry corresponding to the Kafka credential you specified appears on the page.
    The following tabs collect examples of different Kafka credentials as well as some notes regarding configuration. Review these examples to better understand how to correctly configure a Kafka credential.
    name=uswest
Bootstrap servers=uswest-node1.cluster.com:9092,uswest-node2.cluster.com:9092,uswest-node3.cluster.com:9092
Security protocol=PLAINTEXT
The co-located Kafka cluster is defined using Kafka credentials.
Add both external and co-located Kafka clusters to Streams Replication Manager’s configuration.
