Support Changes
This section describes the support changes in 10.2.1.
Upgrade Support Changes
In version 10.2.1, Informatica supports upgrade for Informatica big data products only, such as Big Data Management and Big Data Quality. When you upgrade the domain, functionality for traditional products such as PowerCenter and Informatica Data Quality will not be available.
If you run traditional and big data products in the same domain, you must split the domain before you upgrade. When you split the domain, you create a copy of the domain so that you can run big data products and traditional products in separate domains. You duplicate the nodes on each machine in the domain. You also duplicate the services that are common to both traditional and big data products. After you split the domain, you can upgrade the domain that runs big data products.
Note: Although Informatica traditional products are not supported in version 10.2.1, the documentation does contain some references to PowerCenter and Metadata Manager services.
Big Data Hadoop Distribution Support
Informatica big data products support a variety of Hadoop distributions. In each release, Informatica adds, defers, and drops support for Hadoop distribution versions. Informatica might reinstate support for deferred versions in a future release.

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.
