The Data Integration Service validates whether the mapping can run in the selected environment.
You can deploy the mapping and run it in the selected environment. You can run standalone mappings or mappings that are a part of a workflow.
When you run a mapping in the native environment, the Data Integration Service runs the mapping from the Developer tool.
When you run a mapping on a Hadoop cluster, you can select the Blaze, Spark, or Hive engine. The Data Integration Service pushes the mappings to the selected engine for processing.
