Select the execution environment to use when the mapping runs. When you run a mapping in the native environment, the Data Integration Service processes the mapping. If you installed Big Data Management, you can run a mapping in the Hadoop environment. The Data Integration Service pushes the processing to nodes on a Hadoop cluster. When you select the Hadoop environment, you can also select the engine to push the mapping logic to the Hadoop cluster.

You can use a mapping parameter to indicate the execution environment. Configure a string parameter. When you select the execution environment, click

Assign Parameter

, and select the parameter that you configured.

When you choose the execution environment, the Developer tool saves one of the associated validation environments for the mapping run.
