These properties are used to configure tHMapRecord running in the Spark Streaming Job framework.

The Spark Streaming tHMapRecord component belongs to the Processing family.

The component in this framework is available in Talend Real Time Big Data Platform and in Talend Data Fabric.

Basic settings


To connect to an HDFS installation, select the Define a storage configuration component check box and then select the name of the component to use from those available in the drop-down list.

This option requires you to have previously configured the connection to the HDFS installation to be used, as described in the documentation for the tHDFSConfiguration component.

If you leave the Define a storage configuration component check box unselected, you can only convert files locally.

Open Map Editor

Click the [...] button to open the tHMap Structure Generate/Select wizard where you can either have the hierarchical mapper structure generated automatically based on the schema, or select an existing hierarchical mapper structure. You must do this for both the input and output sides of your Map.

When you connect multiple output connections to the tHMap, the page displays a confirmation message that informs you that the mapper structures are generated based on the output connections.

For more information, see Talend Data Mapper User Guide.

Map Path

Click [...] to select an existing map. The window displays a wizard that allows you to select a map from the Hierarchical Mapper view of Talend Data Mapper.

Die on error

Select the check box to stop the execution of the Job when an error occurs.

Clear the check box to skip any error and continue the Job execution process.


Usage rule This component is used with a tHDFSConfiguration component which defines the connection to the HDFS storage, or as a standalone component for mapping local files only.
Drag-and-drop feature If you have an existing tHMapRecord map in the Data Mapping view, you can easily drag-and-drop the map:
  • When you drag-and-drop the tHMapRecord map into the design workspace, the tHMapRecord component is automatically created
  • When you drag-and-drop the tHMapRecord map into an existing tHMapRecord component, the label and the map reference of the component are automatically updated
Usage with Talend Runtime If you want to deploy a Job or Route containing a data mapping component with Talend Runtime, you first need to install the Talend Data Mapper feature. For more information, see Using Talend Data Mapper with Talend Runtime.
