A cluster configuration is an object in the domain that contains configuration information about the Hadoop cluster. The cluster configuration enables the Data Integration Service to push mapping logic to the Hadoop environment.
When you create the cluster configuration, you import cluster configuration properties that are contained in configuration site files. You can import these properties directly from a cluster or from a cluster configuration archive file. You can also create connections to associate with the cluster configuration.
Previously, you ran the Hadoop Configuration Manager utility to configure connections and other information to enable the Informatica domain to communicate with the cluster.
For more information about cluster configuration, see the "Cluster Configuration" chapter in the
Informatica Big Data Management 10.2 Administrator Guide.
