When you create a cluster configuration, you can choose to create connections. All cluster type 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 when you create a cluster configuration associated with the Hadoop environment:
Hive
HBase
Hadoop
HDFS
The wizard creates a Databricks connection when you create a cluster configuration associated with the Databricks environment.
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.
