Mapping Run-time Properties

Mapping Run-time Properties

The mapping run-time properties depend on the environment that you select for the mapping.
The mapping properties contains the
Validation Environments
 area and an
Execution Environment
 area. The properties in the
Validation Environment
indicate whether the Developer tool validates the mapping definition for the native execution environment, the Hadoop execution environment, or both. When you run a mapping in the native environment, the Data Integration Service processes the mapping.
When you run a mapping in the Hadoop environment, the Data Integration Service pushes the mapping execution to the Hadoop cluster through a Hadoop connection. The Hadoop cluster processes the mapping.
The following image shows the mapping
Run-time
properties in a Hadoop environment: The run-time tab contains a Validation Environments panel and an Execution Environment panel. On the left side is the Validation Environments section. On the right side is the Execution Environment section.
