You can check the status of the cluster through emr_job_flow_sensor.
In the current version, the EmrCreateJobFlowOperator only performs create_job_flow.

> Key: AIRFLOW-5328
> URL: https://issues.apache.org/jira/browse/AIRFLOW-5328
> Project: Apache Airflow
> Issue Type: Bug
> Components: aws, operators
> Affects Versions: 1.10.4
> Reporter: Elad
> Priority: Major
>
> EmrCreateJobFlowOperator returns almost instantly.
> It shouldn't return until the Emr cluster id ready.
> It doesn't make sense to submit tasks to EMR when the cluster isn't ready.
> Currently, tasks are submitted and waiting until the cluster will finish its initialization.
> This can be checked with Waiter:
> [https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/emr.html]
> something like:
> {code:java}
> waiter = client.get_waiter('cluster_running').wait(ClusterId=response['JobFlowId'], WaiterConfig={'Delay': 32, 'MaxAttempts': 60}){code}
