You are connecting to a secure Hadoop dueler from Pentaho and want to use impersonation. Which Pentaho tool should you use?

Pentaho Spoon, also known as Pentaho Data Integration (PDI), is the design tool used to create ETL (Extract, Transform, Load) jobs and transformations. When connecting to a data source like a secure Hadoop cluster, Spoon provides the graphical interface to configure the connection details. This includes setting up security parameters such as Kerberos authentication and enabling user impersonation, which allows a Pentaho job to run on the Hadoop cluster as a specific end-user.

A. Pentaho Report Designer: This tool is for creating pixel-perfect reports. It consumes data connections but is not the primary tool for configuring complex, low-level security settings like Hadoop impersonation.

C. Pentaho Security Manager: This is a component for managing the Pentaho platform's internal security, such as users, roles, and permissions, not for configuring security for external data source connections.

D. Pentaho Server: The Pentaho Server is the execution environment where jobs, transformations, and reports are published and run. The connection configurations themselves are designed and created in Spoon.

Pentaho 9.3

"Set up connections to Hadoop": This official guide details the process of creating and configuring a connection to a Hadoop cluster. The entire procedure

including security configuration for Kerberos and impersonation

is performed within the Pentaho Spoon (PDI) client. The "Hadoop cluster" connection dialog

which contains these settings

is a core feature of Spoon. (See section: Connect to a Hadoop cluster with PDI).

Pentaho 9.3

"Hadoop cluster": This document describes the specific fields within the Hadoop cluster connection window in Spoon. It explicitly mentions configuring security settings

which is where impersonation would be enabled as part of the Kerberos or other security protocol setup. (See section: Hadoop cluster window

specifically the Security tab description).
