Reading Data from Vertica Sources through Sqoop

Reading Data from Vertica Sources through Sqoop

To read Vertica data through Sqoop connectivity, Sqoop requires a custom query.
Create the custom query with the
$CONDITIONS
 parameter in the WHERE clause. Then, define a mapping parameter with the name as
CONDITIONS
 and set its value to
$CONDITIONS
. At run time, Sqoop replaces
$CONDITIONS
 with a unique condition expression.
  1. Open the Sqoop data object and click the
    Query
     tab in the
    Properties
     view.
  2. Define a custom query and include
    $CONDITIONS
     in the WHERE clause of the custom query as shown in the following image: The image shows a dummy custom query that contains $CONDITIONS in the WHERE clause.
  3. Open the Sqoop mapping and click the
    Parameters
     tab in the
    Properties
     view.
  4. Define a mapping parameter with the name as
    CONDITIONS
     and set its value to
    $CONDITIONS
     as shown in the following image: The image shows a mapping parameter with the name set to CONDITIONS and value set to $CONDITIONS.
