Cluster Configuration and Connections
When you create a cluster configuration, you can choose to create connections. All Hadoop connections used to run a mapping must be associated with a cluster configuration.
If you choose to create connections, the Cluster Configuration wizard associates the cluster configuration with each connection that it creates. The wizard creates the following connections:
The wizard uses the following naming convention when it creates connections: <connection type>_<cluster configuration name>, such as Hive_ccMapR.
If you do not choose to create connections, you must manually create them and associate the cluster configuration with them.
Copying a Connection to Another Domain
When you copy a Hadoop, HDFS, HBase or Hive connection that is associated with a cluster configuration to another domain, you must first create a cluster configuration in the target domain.
Create a cluster configuration with the same name as the one that is associated with the connection in the source domain.
- 1. Identify a connection to copy, and note the name of the cluster configuration that is associated with it.
- 2. In the target domain, create a cluster configuration of the same name.
- 3. Choose not to create connections with creation of the cluster configuration.
- 4. Copy the connection to the target domain.
The connection has an associated cluster configuration.
