# PDI steps and entries included in the Hadoop add-on installation

If you want to use the PDI client to access and manipulate your data on a Hadoop cluster, you must also apply the Hadoop add-on installation. See [Install PDI tools and plugins](https://docs.pentaho.com/install/10.2-install/pentaho-installation-overview-cp/installation-of-the-pentaho-design-tools/install-the-pdi-tools-and-plugins) for instructions to include the add-on.

* Transformation steps
  * Annotate Stream
  * CouchDB Input
  * Hadoop File Input
  * Hadoop File Output
  * HBase Input
