Edit the Cluster Configuration

You can edit property values in a cluster configuration. You can also add user-defined properties, override imported property values, and delete properties within a configuration set.
To edit the cluster configuration, you can access the Edit dialog box for a configuration set on the Active Properties view or the Overridden Properties view. Within the Edit dialog box, you can use the filter control to find properties.
If you edit properties in a cluster configuration that the Data Integration Service used to run a mapping, recycle the Data Integration Service for changes to take effect. For example, if you change the Hadoop distribution version for a cluster configuration that the Data Integration Service used to run a mapping, recycle the Data Integration Service for the change to take effect.

Filtering Cluster Configuration Properties

You can search for properties within a configuration set by using the filter controls.
You can filter properties in the Active Properties view or the Overridden Properties view. You might want to filter properties when a configuration set contains a large number of properties.
  1. 1. In the Active Properties view or the Overridden Properties view, expand a configuration set.
  2. 2. Click the Edit icon on the name bar of the configuration set that you want to edit.
    3. The following image shows the Edit icon for the hdfs-site.xml configuration set:
    The Edit icon for the hdfs-site.xml configuration set is selected.
  3. 3. Enter text in the filter text entry pane above any column, and then click the filter icon. You can search by property, imported value, overridden value.
    4. The following image shows the filter text entry panes and the filter icon:
    Each of the three columns in the Edit hdfs-site.xml dialog box has a filter text pane above the column head. On the far right is the Filter icon.

Overriding Imported Properties

You can override property values or you can update overrides from the Active Properties view or the Overridden Properties view.
    1. Expand the configuration set containing the property that you want to edit.
    2. Click the Edit icon on the name bar of the configuration set that you want to edit.
    The Edit dialog box opens.
    3. Optionally, use the filter controls to find a property.
    4. Select the property to edit and click Edit.
    The Edit Property dialog box opens.
    5. Enter a value in the Overridden Value pane, and click OK.
    The following image shows the overridden value in the Edit dialog box:
    After you override the imported value of a property, the Edit dialog box shows both the imported value and the override value.

Creating User-Defined Properties

You can create user-defined properties in the Active Properties view or the Overridden Properties view. When you create a user-defined property, you configure an overridden value. You cannot configure an imported value in a user-defined property.
You can create a user-defined property based on your requirements.
  1. 1. Expand the configuration set where you want to create a property.
  2. 2. Click the Edit icon on the name bar of the configuration set that you want to edit.
    3. The Edit dialog box opens.
  3. 3. Click New.
    4. The New Property dialog box opens.
    The New Property dialog box displays the property name as the Property Key. The image shows a value of rt_ typed in the Overridden Value text entry pane.
  4. 4. Configure the following properties:
    5. Property
    Description
    Property Key
    Name of the property that you want to enter.
    Overridden Value
    The property value.
    To clear the contents of this field, select Clear overridden value.
    Important: If you create a property with the same name as a property that exists in a different configuration set, the Data Integration Service might use either property at run time, leading to unpredictable results.
  5. 5. Click OK.

Deleting Cluster Configuration Properties

You can delete imported and user-defined properties from a configuration set.
    1. Select a cluster configuration to edit.
    2. In the Active Properties view or the Overridden Properties view, expand a configuration set.
    3. Click the Edit icon on the name bar of the configuration set that you want to edit.
    The configuration set expands to show its contents.
    4. Optionally, use the filter control at the top of the Property Key column to filter the properties.
    5. Select the property and click Delete.
Note: Imported properties that you delete will be restored if you refresh the cluster configuration.
