You are running a PDI Job and you need to identify when something fails for a specific job entry to notify the sysops team about the failure. Which…

In Pentaho Data Integration (PDI), job workflow is controlled by hops that connect job entries. To execute a specific action, such as sending a notification, only when a job entry fails, you must use the "On Failure" hop. This hop type is represented by a red arrow and is also referred to as the "false evaluation" hop. It ensures that the subsequent job entry (e.g., a "Mail" or "Write to Log" step) is triggered exclusively upon the failure of the preceding entry, which directly addresses the scenario's requirement for failure-specific notification.

A. Define the true evaluation hop out of the job entry that you are going to verify.

This hop (On Success) executes the next step only when the job entry completes successfully, which is the opposite of the required failure-based trigger.

C. Define the unconditional evaluation hop out of the job entry that you are going to verify.

This hop executes the next step regardless of success or failure, so it cannot be used to specifically identify and act upon a failure event.

D. Do not define any evaluation hop out of the Job entry that are going to verify.

This would terminate the workflow path after the job entry, preventing any subsequent notification step from being executed at all.

"Jobs". This official guide explains the fundamental components of PDI jobs. In the section describing job workflow

it details the different types of hops. It specifies that hops can be conditional based on the success (true) or failure (false) of the previous job entry. The "On Failure" hop is explicitly designated for error handling routines.

"Working with Jobs" section. This document provides practical instructions for building jobs. It illustrates how to create a hop between two job entries and presents the dialog to choose the evaluation condition: "Follow when result is true" (Success)

"Follow when result is false" (Failure)

or "Unconditional". This directly supports using the "false" condition for failure paths.
