Effective in version 10.5.3, the Informatica installer doesn't include Hadoop or Databricks integration packages in the installer files. You can choose the packages that you want and install them along with Informatica installer or later through the Integration Package Manager. You can install the packages when you install, upgrade, or apply the hotfix to Informatica services and the Informatica clients.
The Informatica domain and client require the integration packages to push processing to Hadoop or Databricks, to process complex files within the Informatica domain, or to connect to Hadoop when you process within the Informatica domain.
For more information, see the Informatica installation guides.
