Shell nodes support standard shell syntax but not interactive syntax.

Background information

You can run Shell nodes only on exclusive resource groups for scheduling. For more information, see Create and use an exclusive resource group for scheduling.

A Shell node that is run on an exclusive resource group for scheduling may need to access a data source that has a whitelist. In this case, you must add the information about the resource group to the whitelist of the data source. For more information, see Add the exclusive resource group for scheduling to the whitelist of the data store to be accessed.

Procedure

  1. Go to the DataStudio page.
    1. Log on to the DataWorks console.
    2. In the left-side navigation pane, click Workspaces.
    3. In the top navigation bar, select the region where the required workspace resides, find the workspace, and then click Data Analytics.
  2. On the Scheduled Workflow tab, move the pointer over the Create icon and choose General > Shell.
    Alternatively, you can click a workflow in the Business Flow section, right-click General, and then choose Create > Shell.
  3. In the Create Node dialog box, set the Node Name and Location parameters.
    Note The node name must be 1 to 128 characters in length and can contain letters, digits, underscores (_), and periods (.).
  4. Click Commit.
  5. Configure the Shell node.
    1. Write the code of the Shell node in the code editor.
      To use the system scheduling parameters in the Shell node, execute the following statement: 
      echo "$1 $2 $3"
      Note Separate multiple parameters with spaces. Example: Parameter1 Parameter 2. For more information about the system scheduling parameters, see Configure scheduling parameters.
    1. Click the Save icon in the top toolbar to save the SQL statements.
    2. Click the Run icon in the toolbar to execute the SQL statements that you have saved.
      If you want to use another resource group to test the Shell node on the DataStudio page, click the Run with parameters icon in the toolbar and select the exclusive resource group to use.
  6. On the node configuration tab, click the Properties tab in the right-side navigation pane. On the Properties tab, set the scheduling properties for the node. For more information, see Configure basic properties.

    Notice You must set the Rerun and Parent Nodes parameters before you can commit the node.
    1. Click the Save icon in the toolbar to save the node.
    2. Click the Commit icon in the toolbar.
    3. In the Commit Node dialog box, enter your comments in the Change description field.
    4. Click OK.
    In a workspace in standard mode, you must click Deploy in the upper-right corner after you commit the node. For more information, see Deploy nodes.
  8. Test the node. For more information, see View auto triggered nodes.
