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:
Hive
HBase
Hadoop
HDFS
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.
