> EmrStepSensor marks cancelled step as successful
> -------------------------------------------------
>
> Key: AIRFLOW-3297
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3297
> Project: Apache Airflow
> Issue Type: Bug
> Reporter: Dana Assa
> Assignee: Dana Assa
> Priority: Minor
> Fix For: 2.0.0, 1.10.1
>
>
> When a step is manually cancelled or when the cluster is terminated
> unexpectedly, an EMR step can reach 'CANCEL_PENDING' state or 'INTERRUPTED'
> state.
> These states are not mentioned as FAILED_STATES nor as NON_TERMINAL_STATES in
> the "EmrStepSensor" class, thus the sensor returns True and the Airflow stage
> is marked as success instead of failed.
