In version 10.1.1 HotFix 2, Informatica supports upgrade for Informatica traditional products only, such as PowerCenter and Data Quality.
You cannot apply the hotfix to a domain that runs big data products. Big data products include Big Data Management, Big Data Quality, Enterprise Information Catalog, Intelligent Data Lake, Big Data Parser, and Intelligent Streaming.
If you run traditional and big data products in the same domain, you must split the domain before you apply the hotfix. 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 apply the hotfix to the domain that runs traditional products.
You cannot split a domain if the Model repository is integrated with a third-party version control system.
Although Informatica big data products are not supported in 10.1.1 HotFix 2, the documentation does contain references to Hadoop and other big data terminology.
