Procedure

  1. In the Integration perspective of the Studio, create an empty Map/Reduce Job from the Job Designs node in the Repository tree view.
    For further information about how to create a Map/Reduce Job, see Talend Open Studio for Big Data Getting Started Guide .
  2. Drop a tHDFSInput component, a tJavaMR component, and a tHDFSOutput component in the workspace.
    The tHDFSInput component reads data from the Hadoop distribution to be used and the tHDFSOutput component writes processed data into a that distribution.
  3. Connect these components using the Row > Main link.
