After you choose the Hadoop option, you can select a Hadoop connection. The Data Integration Service pushes the profile logic to the Blaze engine on the Hadoop cluster to run profiles.

When you run a profile in the Hadoop environment, the Developer tool submits the profile jobs to the Profiling Service Module. The Profiling Service Module then breaks down the profile jobs into a set of mappings. The Data Integration Service pushes the mappings to the Hadoop environment through the Hadoop connection. The Blaze engine processes the mappings and the Data Integration Service writes the profile results to the profiling warehouse.
