Adding field comments in dataset

When working with large datasets data, it can be useful to have access to comprehensive field-level descriptions. In Cloudera Data Visualization, you can use field comments to provide the context and meaning of each dataset field.

The following steps demonstrate how to add description to a column of a dataset, as a 'comment'. In this example, the county field is used from the Food Stores Inspection in NYC dataset.

    The Data view opens, displaying the Datasets tab.

  2. Select a connection from the connection list on the left side panel.
  3. In the Datasets area, click the dataset you want to modify.
  4. In the Dataset Detail menu, select Fields.
  5. Click Edit to access the editing interface.
  6. Under Dimensions, find the field county and click .

    The Edit Field Parameters modal opens.

  7. Add your comment in the Field Comment text box.
  8. Click Apply.
  9. Click Save.
  10. Optional: Click Show Comments to display the field comment.

    To hide field comments, you can click Hide Comments.
