   > If you need to use xcom push, just make the init container yourself in the 
spark operator template (based on 
https://github.com/apache/airflow/blob/main/airflow/providers/cncf/kubernetes/utils/xcom_sidecar.py)
   > 
   > ```
   >   volumes:
   >       - name: xcom
   >         emptyDir: {}  
   >   driver:
   >     volumeMounts:
   >       - name: xcom
   >         mountPath: /airflow/xcom
   >     sidecars:
   >       - name: airflow-xcom-sidecar

   @creyer I tried this however it still stays stuck for xcom push, do we have 
to enable something else in the spark operator for this to work? Did you add 
this in initContainers section or sidecars like you have it above?
