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 the Hadoop environment and a Hadoop connection.
  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.
    The
    Hive on MapReduce
    and
    Blaze
    engines are selected by default. To only use the
    Hive on MapReduce
    engine, clear the
    Blaze
    engine. If you use the
    Blaze
    engine, you cannot clear the
    Hive on MapReduce
    engine.
  4. In the execution environment, select
    Hadoop
    .
    The figure shows the mapping Run-time tab. Under Validation Environment, Hadoop is selected. The Hive on MapReduce and Blaze engines are selected by default. Under Execution Environment, Hadoop is selected.
  5. In the Hadoop environment, select
    Connection
    and use the drop down in the value field to browse for a connection or select a connection parameter:
    • To select a connection, click
      Browse
      and select a connection.
    • To select a connection parameter, click
      Assign Parameter
      .
    The figure shows the Validation Environments and Execution Environments. In the Execution Environment, Connection and Execution Parameters appear under Hadoop. In the Value field for the connection, the drop down list shows Browse and Assign Parameter.
  6. Optionally, select
    Execution Parameters
    and select a Hadoop connection parameter that you defined on the
    Parameters
    tab for the mapping.
  7. Right-click an empty area in the editor and click
    Run Mapping
    .
