Pair clusters for replication

You must pair two clusters to communicate with one another before you can replicate data between the clusters. After the clusters are paired, you can create a replication policy.

Knox proxying can only be enabled on paired clusters running DLM Engine version 1.1 or higher.

Pairing clusters only establishes a communication relationship between two clusters. You determine which cluster of that pair is the source and which is the destination when you create the replication policy.

You must be logged in with the DLM Infra Admin role to perform this task.
Before pairing, clusters must have been enabled for use with Data Lifecycle Manager from the DPS Platform UI.
The clusters you want to pair must have symmetrical security configurations for Kerberos, LDAP, Ranger, Knox, HA, etc.

In the DLM navigation pane, click Pairings.
Click Add Pairing.
The Create Pairing page displays, showing the clusters that are enabled for replication.
Tip
You can place the cursor over the cluster name to display the cluster location.
Click one of the cluster names.
All clusters available to be paired with the cluster you selected display in a second column.
Tip
If a cluster displays but cannot be selected, it is already paired with the cluster you selected in the first column.
Click a cluster in the second column.
Click Start Pairing.
A progress bar displays.
Repeat the above steps to pair additional clusters.
