ElasticMapReduce: Specified Availability Zone is not supported

Question

I tried to use EMR in Oregon region so I used "us-west-2" as availability zone in run_job_flow and I got the following error:

Error response for action RunJobFlow: Sender/ValidationError; Specified Availability Zone is not supported

Answer 1

"us-west-2" is the name of a region and NOT the name of an availability zone.

Use either "us-west-2a" or "us-west-2b"
