Amazon RedShift Copy Command

Specify the source region as below

copy pep.test 
(operation, task_id, task_name)
from 's3://move-redshift-data-devo/move-redshift-data-devo/'
iam_role 'arn:aws:iam::355750824903:role/RedshiftDynamoDBAccess'
format as csv
region as 'us-east-1';

The S3 bucket and redshift must be in the same region (US East):

This example uses an Amazon S3 bucket that is located in the US East (Northern Virginia) region. When you load data using a COPY command, the bucket containing your data must be in the same region as your cluster.

If your redshift cluster is in another region, look at Step 5: Load Sample Data from Amazon S3, scrolling to the table with region-specific-bucket-name:
