A distribution package is a set of distribution binaries that you install within the domain for the following processing requirements:

To push processing to the Hadoop or Databricks environment.
To process complex files within the Informatica domain.
To connect to the Hadoop or Databricks environment when you process within the Informatica domain.

You can install distribution packages if you didn't do so during the upgrade or install process or if you want to add a distribution package. You can remove a distribution package if you want to use a different package or if you installed a package that you don't use.

When you install or remove distribution packages, verify that you perform the operation on all service and client machines.
