Ash Berlin-Taylor updated AIRFLOW-4484:
---------------------------------------
Description:
We're seeing a quite a few process time outs raising during our core pipeline
run. We traced it back to CeleryExecutor#sync calling #fetch_celery_task_state
and timing out here:
airflow/utils/timeout.py:
{code:python}
def handle_timeout(self, signum, frame):
self.log.error("Process timed out, PID: %s", str(os.getpid()))
raise AirflowTaskTimeout(self.error_message)
{code}
called from here: airflow/executors/celery_executor.py#fetch_celery_task_state
{code:python}
with timeout(seconds=2):
# Accessing state property of celery task will make actual network request
# to get the current state of the task.
res = (celery_task[0], celery_task[1].state)
{code}
along with an AirflowTaskTimeout raising here:
airflow/executors/celery_executor.py#heartbeat
{code:python}
if isinstance(result, ExceptionWithTraceback):
self.log.error(
CELERY_SEND_ERR_MSG_HEADER + ":{}\n{}\n".format(
result.exception, result.traceback))
{code}
This code was introduced in this new feature:
https://issues.apache.org/jira/browse/AIRFLOW-2761
Are there configuration settings that we need to set as a result of this new
code to avoid these timeouts?
