the sink result is loaded with :
resultB = tableA.flat_map(name).alias('name') \
.select(col('name'))\
.execute_insert('allowed_table').wait()
resultA = tableA.flat_map(name).alias('name') \

I solved this problem by removing .wait()

I'm running Airflow with Docker swarm on 5 servers. After using 2 months, there are some errors on Dags like this. These errors occurred in dags that using a custom hive operator (similar to the inner function ) and no error occurred before 2 months. (Nothing changed with Dags...)
Also, if I tried to retry dag, sometimes it succeeded and sometimes it failed.
The really weird thing about this issue is that hive job was not failed. After the task was marked as failed in the airflow webserver (Sigterm), the query was complete after 1~10 mins.
As a result, flow is like this.
Task start -> 5~10 mins -> error (sigterm, airflow) -> 1~10 mins -> hive job success (hadoop log)

I already restarted the airflow server and there was nothing changed.
Here is the failed task's log (flower log)
Is there any helpful guide for me?
Thanks :)

Any help please?
I got two solution for this from here, one is to remove the pid file /var/run/nginx-nr-agent/nginx-nr-agent.pid and than start/restart it. And second solution is to restart the server.
