Reading and caching the sample data

  3. Click OK to validate these changes and accept the
    propagation prompted by the pop-up dialog box.
  4. Select the Define a storage configuration
    component     check box and select the tHDFSConfiguration component to be used.

    tFileInputDelimited uses this configuration
    to access the sample data to be used as training set.
  5. In the Folder/File field, enter the directory
    where the training set is stored.
  6. Double-click the tReplicate component to open its
    Component view.
  7. Select the Cache replicated RDD check box and from
    the Storage level drop-down list, select
    Memory only. This way, this sample data is
    replicated and stored in memory for use as test set.
