The default value is currently 10. But it's hard coded. I've created https://issues.apache.org/jira/browse/SQOOP-1657 to track this.
You can set the throttling count to set the number of mappers. This puts a "max" on the number of partitions that can be generated (or should be). There is a negotiation between the Sqoop2 driver and the connector. If the connector returns more than the defined extractor throttling number, an error is thrown. Otherwise, the job will continue. -Abe On Mon, Nov 3, 2014 at 4:19 AM, Sambit Tripathy (RBEI/PJ-NBS) < [email protected]> wrote: > Hi, > > How to control the number of Mappers in Sqoop 2?
