Changing the Hadoop Cluster for a Mapping Run

Changing the Hadoop Cluster for a Mapping Run

You can change the Hadoop cluster that a mapping runs on.
You might want to change the Hadoop cluster to run the mapping on a different Hadoop cluster type or different version.
To change the Hadoop cluster that a mapping runs on, click the connection where it appears in the mapping Run-time properties. Then click
Browse
, and select a Hadoop connection that uses a cluster configuration for the cluster you want the mapping to run on.
The following image shows the
Browse
 choice for a Hadoop connection:
The mapping Run-time properties display the Hadoop connection in the Execution Environment section. Click the edit arrow on the right of the property value pane to select Browse.
After you change the connection that the mapping uses, you must restart the Data Integration Service for the change to take effect.
