Selecting the files

  1. Double-click tHDFSGet to open its
    Component view.

  2. In the Version area, select the Hadoop
    distribution you are connecting to and its version.
  3. In the Connection area, enter the values
    of the parameters required to connect to the HDFS.

    In the real-world practice, you may have used tHDFSConnection to create a connection; then you can reuse
    it from the current component. For further information, see tHDFSConnection.
  4. In the HDFS directory field, enter the
    path to the folder holding the files to be retrieved.

    To do this with the auto-completion list, place the mouse pointer in this
    field, then, press Ctrl+Space to display
    the list and select the
    tHDFSList_1_CURRENT_FILEDIRECTORY     variable to reuse the
    directory you have defined in tHDFSList. In
    this variable, tHDFSList_1 is the label
    of the component. If you label it differently, select the variable
    accordingly.
    Once selecting this variable, the directory reads, for example, ((String)globalMap.get(“tHDFSList_1_CURRENT_FILEDIRECTORY”))
    in this field.
    For further information about how to label a component, see the
    Talend Studio

    User
    Guide    .
  5. In the Local directory field, enter the
    path, or browse to the folder you want to place the selected files in. This
    folder will be created if it does not exist. In this example, it is
    C:/hdfsFiles.
  6. In the Overwrite file field, select
    always.
  7. In the Files table, click

    to add one row and enter * between the quotation marks in the Filemask column in order to get any files existing.
