Select a Hadoop connection to push the profile logic to the Blaze or Spark engine to run a profile. When you run a profile on the Blaze or Spark engine, the Analyst tool or Developer tool submits the profile job 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 or Spark engine processes the mappings and the Data Integration Service writes the profile results to the profiling warehouse.
In the Developer tool, you can run single object profiles and multiple object profiles, and enterprise discovery profiles on the Blaze or Spark engine. In the Analyst tool, you can run column profiles, enterprise discovery profiles, and scorecards on the Blaze or Spark engine.
