You can run a mapping in the native environment. In the native environment, the Data Integration Service runs the mapping from the Developer tool. You can run standalone mappings or mappings that are a part of a workflow.
In the native environment, you can read and process data from large unstructured and semi-structured files, Hive, or social media web sites. You can include the following objects in the mappings:
Hive sources
Flat file sources or targets in the local system or in HDFS
Complex file sources in the local system or in HDFS
Data Processor transformations to process unstructured and semi-structured file formats
