zeroam commented on pull request #7719: [AIRFLOW-7060] remove environment value
AIRFLOW__CORE__EXECUTOR in backend-sqlite.yml
URL: https://github.com/apache/airflow/pull/7719
Because the default breeze environment set `AIRFLOW_CORE_EXECUTOR` to
`SequentialExecutor`, I can't change it to 'CeleryExecutor' through
airflow.cfg.

> EXECUTOR variable don't work in airflow.cfg in breeze shell
> -----------------------------------------------------------

> Key: AIRFLOW-7060
> URL: https://issues.apache.org/jira/browse/AIRFLOW-7060
> Project: Apache Airflow
> Issue Type: Bug
> Components: celery, cli
> Affects Versions: 2.0.0
> Reporter: JeonChangWon
> Assignee: JeonChangWon
> Priority: Major
> Labels: pull-request-available
>
> Because the default breeze environment set `AIRFLOW__CORE__EXECUTOR` to
> `SequentialExecutor`, I can't change it to 'CeleryExecutor' through
> airflow.cfg.
> Problem 1:
> When I execute the command `airflow celery` in the breeze default
> environment, an error occurred. Because the `celery` command is added
> dynamically when the executor is set to CeleryExecutor by airflow.cfg.
> {code:java}
> if conf.get("core", "EXECUTOR") == ExecutorLoader.CELERY_EXECUTOR or
> BUILD_DOCS: ...{code}
>
> So, I changed airflow.cfg file from SequentialExecutor to CeleryExecutor.
> but above error still exist because of the environment variable
> `AIRFLOW__CORE__EXECUTOR` which is set to "SequentialExecutor" by
> 'backend-sqlite.yml' file
>
> Problem 2:
> In addition, the below error can occur after I changed
> `AIRFLOW__CORE__EXECUTOR` to "CeleryExecutor" because "Celery Executor" don't
> use sqlite.
> {code:java}
> Traceback (most recent call last): File "/usr/local/bin/airflow", line 7, in
> <module> exec(compile(f.read(), __file__, 'exec')) File
> "/opt/airflow/airflow/bin/airflow", line 26, in <module> from airflow.bin.cli
> import CLIFactory File "/opt/airflow/airflow/__init__.py", line 34, in
> <module> from airflow import settings File
> "/opt/airflow/airflow/settings.py", line 34, in <module> from
> airflow.configuration import AIRFLOW_HOME, WEBSERVER_CONFIG, conf # NOQA F401
> File "/opt/airflow/airflow/configuration.py", line 602, in <module>
> conf.read(AIRFLOW_CONFIG) File "/opt/airflow/airflow/configuration.py", line
> 309, in read self._validate() File "/opt/airflow/airflow/configuration.py",
> line 185, in _validate self.get('core', 'executor')))
> airflow.exceptions.AirflowConfigException: error: cannot use sqlite with the
> CeleryExecutor{code}
>
> Solution 2:
>
> I execute breeze command with an option like
> {code:java}
> ./breeze -i redis -b postgres{code}
> And change airflow.cfg SequentialExecutor to CeleryExecutor.
> I finally could use the celery command and the celery worker works well.
>
>
> I will send PR for Problem 1
