perspective of the Studio, create an empty
Spark Batch Job from the Job Designs node in
the Repository tree view.
For further information about how to create a Spark Batch Job, see Talend Open Studio for Big Data Getting Started Guide .
In the workspace, enter the name of the component to be used and select this
component from the list that appears. In this scenario, the components are
tHDFSConfiguration, tMongoDBConfiguration, tFixedFlowInput, tMongoDBOutput,
tMongoDBInput and tLogRow.
The tFixedFlowInput components are used to load the sample data into the data flow. In the real-world practice, you can use other components such as tFileInputDelimited, alone or even with a tMap, in the place of tFixedFlowInput to design a sophisticated process to prepare your data to be processed.
- Connect tFixedFlowInput to tMongoDBOutput using the Row > Main link.
- Connect tMongoDBInput to tLogRow using the Row > Main link.
- Connect tFixedFlowInput to tMongoDBInput using the Trigger > OnSubjobOk link.
- Leave tHDFSConfiguration and tMongoDBConfiguration alone without any connection.
