Configure Run-time Engines
You can run mappings in the Informatica native environment or the Hadoop environment. You must choose a run-time engine to run mappings in the Hadoop environment.
When you choose the native environment, Big Data Management uses the Data Integration to run mappings on the Informatica domain. When you choose the Hadoop environment, the Data Integration Service pushes the mapping to the cluster.
When you want to run mappings in the Hadoop environment, you choose from the following run-time engines:
- Blaze engine
- The Blaze engine is an Informatica software component that can run mappings on the Hadoop cluster.
- Spark engine
- Spark is an Apache project that provides a run-time engine that can run mappings on the Hadoop cluster.
- Hive engine
- The Hive engine uses the Hive driver mode to run mappings on the Hadoop cluster.
Informatica recommends that you select all engines to run mappings in the Hadoop environment. The Data Integration Service uses a proprietary rule-based methodology to determine the best engine to run the mapping. The rule-based methodology evaluates the mapping sources and the mapping logic to determine the engine.
Note: Effective in version 10.1.1, the Hive engine no longer supports the HiveServer2 mode to run the mappings. If you install Big Data Management 10.1.1 or upgrade to version 10.1.1, you can continue to use the Hive engine in the Hive driver mode.
