Configuring a Mapping to Run in a Hadoop Environment

Configuring a Mapping to Run in a Hadoop Environment

You can configure a mapping to run in a Hadoop environment. To configure a mapping, you must select a validation environment and an execution environment.
Hive engine is deprecated and Informatica plans to drop support in a future release.
  1. Select a mapping from a project or folder from the
    Object Explorer
    view to open in the editor.
  2. In the
    Properties
    view, select the
    Run-time
    tab.
  3. Select
    Hadoop
    as the value for the validation environment.
    By default, the Blaze and Spark engines are selected. Disable the engines that you do not want to use.
  4. Select
    Hadoop
    for the execution environment.
    The Run-time tab contains a Validation Environments panel and an Execution Environments panel.
  5. In the Hadoop environment, select
    Connection
    and use the drop down in the value field to browse for a connection or create a connection parameter:
    • To select a connection, click
      Browse
      and select a connection.
    • To create a connection parameter, click
      Assign Parameter
      .
  6. Configure the rest of the properties for the Hadoop execution environment.
  7. Right-click an empty area in the editor and click
    Validate
    .
    The Developer tool validates the mapping.
  8. View validation errors on the
    Validation Log
    tab.
  9. Click the
    Data Viewer
    view.
  10. Click
    Show Execution Plan
    to view the execution plan for the mapping.
