    steps is properly defined.

    Note that if you are creating this Job from scratch, you need to click the

    plus_button.png

    button to manually define the schema; otherwise, if the
    schema has been defined in Repository, you
    can select the Repository option from the
    Schema list in the Basic settings view to reuse it. For further
    information about how to define a schema in Repository, see the chapter describing metadata management
    in the
    Talend Studio User Guide     or the chapter describing the
    Hadoop cluster node in Repository of
    Talend Open Studio for Big Data Getting Started
    Guide
    .

  3. If you make changes in the schema, click OK to validate these changes and accept the propagation
    prompted by the pop-up dialog box.
  4. In the Folder/File field, enter the path,
    or browse to the source file you need the Job to read.

    If this file is not in the HDFS system to be used, you have to place it in
    that HDFS, for example, using tFileInputDelimited and tHDFSOutput in a Standard
    Job.
