> SparkSubmitOperator polls forever if status json can't find driverState tag
> ---------------------------------------------------------------------------

> Key: AIRFLOW-6229
> URL: https://issues.apache.org/jira/browse/AIRFLOW-6229
> Project: Apache Airflow
> Issue Type: New Feature
> Components: scheduler
> Affects Versions: 1.10.6
> Reporter: t oo
> Assignee: t oo
> Priority: Major
>
> You click ‘release’ on a new spark cluster while the prior spark cluster is
> processing some spark submits from airflow. Then airflow is never able to
> finish the sparksubmit task as it polls from status on the new spark cluster
> build which it can’t find status for as the submit happened on earlier spark
> cluster build….the status loop goes on forever
>
> [https://github.com/apache/airflow/blob/1.10.6/airflow/contrib/hooks/spark_submit_hook.py#L446]
> [https://github.com/apache/airflow/blob/1.10.6/airflow/contrib/hooks/spark_submit_hook.py#L489]
> It loops forever if it can’t find driverState tag in the json response, since
> the new build (pointed to by the released DNS name) doesn’t know about the
> driver submitted (in previously released build) then the 2nd response below
> does not contain the driverState tag.

> "serverSparkVersion" : "2.3.4", "submissionId" :
> "driver-20191202142207-0000", "success" : true, "workerHostPort" :
> "reda:31489", "workerId" : "worker-20191202133526-reda-31489"}

> Definitely a defect in current code. Can fix this by modifying
> _process_spark_status_log function to set driver status to UNKNOWN if
> driverState is not in response after iterating all lines.
