Native and Hadoop Environments

Native and Hadoop Environments

When you run a profile in the native environment, the Analyst tool or 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 runs these mappings and writes the profile results to the profile warehouse.
The native environment runs the mappings on the same machine where the Data Integration Service runs. The Hadoop environment runs the mappings on a Hadoop cluster. The Data Integration Service pushes the mapping execution to the Hadoop cluster through a Hive connection. This environment makes all the sources, transformations, and Hive and HDFS sources available for profile run.
If you choose a native source for the Hadoop run-time environment, the Data Integration Service runs the profile on Hadoop. You cannot run a Hadoop data source in the native run-time environment.
