Today, Amazon EMR on EC2 announced an enhancement to the DescribeStep and ListStep API to allow customers to view up to 10,000 completed steps within the last 7 days, an increase from the previous limit of 1,000 steps. The service will also continue supporting the retrieval of 1,000 steps from the past two months. These API improvements provide greater visibility into completed steps and makes it easier for you to monitor and manage your steps workflow.
