Verify cluster requirements

Before you create a replication policy on your on-premises cluster, you must verify whether the cluster requirements are met.

Cluster requirements to create a replication policy in the Replication Manager include:
  • Registering the CDH on-premise cluster on the Management Console. For more information, see Add a CDH cluster.
  • Verifying whether the Cloudera Manager version is 6.3 and above.
  • Verifying whether the CDH cluster version is 5.13x and above.
  • Verifying whether the following requirements are met for HDFS replication:
    • Ensuring that the Replication Manager service interacts with the classic cluster-registered Cloudera Manager instance.
    • Ensuring that an external account is available in the Cloudera Manager instance that has access to the bucket or container where the HDFS data is being copied to. For more information, see Role-based credential on AWS, App-based credential on Azure, and Cloudera Manager documentation.
  • Verifying whether the following requirements are met for Hive replication:
    • Ensuring that the Replication Manager service interacts with the Data Lake Cloudera Manager instance and vice-versa.
    • Ensuring that in addition to an external account in the Cloudera Manager instance, an IAM external account with bdr as the username in the Data Lake cluster Cloudera Manager instance exists.
    • Ensuring that you have added a classic cluster Cloudera Manager as a source in the Data Lake Cloudera Manager instance. For more information, see Designating a replication source.
