Cloning segments

Cloudera Data Visualization lets you clone an existing segment definition.

  1. On the main navigation bar, click DATA.
  2. Select Flight Delays dataset.
    Dataset side navigation appears, open at Dataset Detail view.
  3. In the side navigation menu, click Segments.
  4. In the Segments list, find the segment to clone, and click Clone.

    In this example, Delayed Flights will be cloned to create a new segment On-Time Departure.

    A pre-populated Add Segment modal window appears named Copy of Delayed Flights.

  5. Edit the Add Segment modal window by changing its entries.
    • Change Segment Name, to On-Time Departure.
    • Leave Segment Group as is.
    • Under Filters, click the text box to open the Filter Expression modal window.
  6. Replace the filter expression. In our example, we are adding the following expression: 
    [airtime] IS NOT NULL AND [depdelay] < = 0
  7. Optional: Click Validate Expression to verify correctness.
  8. Click Apply to save the filter and return to the Add Segment modal window.
  9. Under Filters, notice the new filter expression.
  10. Click Save.
  11. The new segment definition appears in the Segments interface.

    Note the similarity in the definition of the two filters, Delayed Flights and On-Time Departure.
