  4. Click the plus button three times to add three rows and rename them as
    id, name and age respectively
    in the Column column. This means that you
    extract these three columns from the HBase.
  5. Select the types for each of the three columns. In this example, Integer for id
    and age, String for name.
  6. Click OK to validate these changes and
    accept the propagation prompted by the pop-up dialog box.
  7. In the Table name field, type in the
    table from which you extract the columns of interest. In this scenario, the
    table is customer.
  8. In the Mapping table, the Column column has been already filled
    automatically since the schema was defined, so simply enter the name of
    every family in the Column family column,
    each corresponding to the column it contains.
  9. Double-click tHBaseClose to open its
    Component view.
