After you enable Sqoop in a JDBC connection and import a Sqoop source or Sqoop target, you can create a mapping. You can then run the Sqoop mapping in the Hadoop run-time environment with a Hadoop connection. You can run Sqoop mappings on the Blaze, Spark, and Hive engines.
You can run Sqoop mappings on the Spark engine only when you want to read data from or write data to Oracle databases. If you use the Cloudera Connector Powered by Teradata or Hortonworks Connector for Teradata, you must run the mappings on the Blaze engine.
In the mapping, you can specify additional Sqoop arguments and disable the Sqoop connector.
