Creating HDFS replication policy using CDP CLI

You can use CDP CLI to create an HDFS replication policy.

Log into Replication Manager CDP CLI setup using the cdp --profile [***profile-name***] replicationmanager command.
List the clusters to verify whether the required source cluster is available using the cdp --profile [***profile-name***] replicationmanager list-clusters command.
The source cluster CRN is used to create an HDFS replication policy.
Verify whether the required services are running on the source cluster using the cdp --profile [***profile-name***] replicationmanager list-cluster-service-statuses command.
Ensure that the cloud credentials are available using the cdp --profile [***profile-name***] replicationmanager list-all-credentials command.
Open a policy definition JSON file, enter the required parameters to create a policy definition JSON file, and save the file.

tip
Copy the output of the cdp --profile [***profile_name***] replicationmanager create-policy --generate-cli-skeleton command to a JSON file to use it as a policy definition JSON file.

important
Remove the key-value pairs that are not required in the policy definition JSON file for the specific policy. For example, remove the hiveArguments key-value pairs when you create a HDFS policy.
Run the cdp --profile [***profile_name***] replicationmanager create-policy --cli-input-json [****policy definition json file path using cat***] command to create a replication policy.

important
You must use the cat command to read the data from the policy definition JSON file.

For example: cdp --profile local-dev replicationmanager create-policy --cli-input-json “$(cat temp/rm_hdfs_1.json)”

To verify whether the policy is created and running as expected, run the cdp --profile [***profile_name***] replicationmanager list-policies command. You can also open the Replication Manager web interface to view the policy status on the Replication Policies page.
