Create Other Workflow Tasks

Create Other Workflow Tasks

Populate the cluster workflow with at least one Mapping task. You can add Command or other workflow tasks and events.
  1. Drag a Mapping task from the task list to the workflow editor.
    The
    Mapping Task
     dialog box opens.
  2. Name the Mapping task.
  3. Select a mapping to run with the Mapping task. Click
    Browse
     next to the Mapping property, select a mapping, and click
    Finish
    .
  4. Optionally select a parameter set to associate with the Mapping task. Click
    Browse
     next to the Parameter Set property, select a parameter set, and click
    Finish
    .
    For more information on how to use parameter sets with mappings, see the
    Informatica Developer Mapping Guide.
  5. Optionally complete Input and Output properties.
    The Mapping task does not require any unique values for input or output properties.
  6. Configure the Cluster Identifier property in Advanced properties.
    The Cluster Identifier property designates the cluster to use to run the Mapping task.
    The following table describes values for Cluster Identifier properties:
    Value
    Description
    Blank (no value)
    Run the mapping runs on the cluster configured in the Hadoop connection associated with the mapping.
    AutoDeploy
    Run the mapping on the cluster that the workflow creates.
    When you choose this option, it also populates the Cluster Identifier property in the Create Cluster task with the value Set to AutoDeployCluster.
    Default is AutoDeploy.
    (Assign to task input)
    Select this option to accept input from another source than the Create Cluster task. If you choose this option, enter a parameter value in the Cluster Identifier property of the Mapping task Input properties tab.
  7. Click
    Finish
     to the Mapping task.
  8. Optionally add more Mapping and other tasks to the workflow.
    You can include any other workflow tasks in a cluster workflow. For example, you might want to add a Command task to perform tasks after a Mapping task runs.
