Designing the flow of the data to write and encrypt onto EMR

Link the components to construct the data flow.

Procedure

  1. In the Integration perspective of Talend Studio, create an empty Spark Batch Job from the Job Designs node in the Repository tree view.
  2. 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 (labeled emr_hdfs), tS3Configuration, tFixedFlowInput, tAggregateRow and tFileOutputParquet.
    The tFixedFlowInput component is used to load the sample data into the data flow. In the real-world practice, use the input component specific to the data format or the source system to be used instead of tFixedFlowInput.
  3. Connect tFixedFlowInput, tAggregateRow and tFileOutputParquet using the Row > Main link.
  4. Leave the tHDFSConfiguration component and the tS3Configuration component alone without any connection.
