Hive Run-Time Engine

Hive Run-Time Engine

Effective in version 10.2.1, the MapReduce mode of the Hive run-time engine is deprecated, and Informatica will drop support for it in a future release. The Tez mode remains supported.

Mapping

When you choose to run a mapping in the Hadoop environment, the Blaze and Spark run-time engines are selected by default.
Previously, the Hive run-time engine was also selected.
If you select Hive to run a mapping, the Data Integration Service will use Tez. You can use the Tez engine only on the following Hadoop distributions:
  • Amazon EMR
  • Azure HDInsight
  • Hortonworks HDP
In a future release, when Informatica drops support for MapReduce, the Data Integration Service will ignore the Hive engine selection and run the mapping on Blaze or Spark.

Profiles

Effective in version 10.2.1, the Hive run-time engine is deprecated, and Informatica will drop support for it in a future release.
The Hive option appears as Hive (deprecated) in Informatica Analyst, Informatica Developer, and Catalog Administrator. You can still choose to run the profiles on the Hive engine. Informatica recommends that you choose the Hadoop option to run the profiles on the Blaze engine.
