Effective in version 10.0, you can select the Hadoop environment to run mappings on the Hadoop cluster. When you select the Hadoop environment, you can also select the Hive or Blaze engine to push the mapping logic to the Hadoop cluster. The Blaze engine is an Informatica proprietary engine for distributed processing on Hadoop.
When you run a mapping in the Hadoop environment, you must configure a Hadoop connection for the mapping. Validate the mapping to ensure that you can push the mapping logic to Hadoop. After you validate a mapping for the Hadoop environment, you can run the mapping.
