| **Column name**         | The name of the column in the HBase table.

| **Format**              | <p>Applies a formatting mask to the field. A formatting string must be provided for date values involved in a range scan (and optionally for numbers). There are two ways to provide this information in the dialog box:</p><ul><li>Configure the step with fields from the mapping, include the key in the fields to output from the step, then enter a formatting string in the <strong>Format</strong> cell in the row corresponding to the key field.</li><li>If you have not opted to output the key from the step or have opted to output all fields in the mapping by leaving the fields table blank, then you can supply formatting information for the start and stop key values independently by suffixing the start or stop key value with the formatting string following a '@' separator character. For example, a date start key value of 1969-08-28 can be specified as <code>1969-08-28\@yyy-MM-dd</code>.</li></ul> |
| **Indexed values**      | An optional set of values you can define for string columns by entering comma-separated data in this field.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |
