Airflow CLI throwing plugin logs as output

[abhishekbhakat]

Apache Airflow version

2.6.1

What happened

Tried this with Airflow 2.6.1 and some plugins installed (eg: openlineage-airflow)

When we try to run a command airflow variables get test it shows Warning logs with the output.

docker run -it quay.io/astronomer/astro-runtime:8.2.0 bash
astro@b823037e7206:/usr/local/airflow$ a=`airflow variables get test`
Variable test does not exist
astro@b823037e7206:/usr/local/airflow$ echo $a

I think the issue is how Airflow plugins handle logs.

What you think should happen instead

The expected output should be:

docker run -it quay.io/astronomer/astro-runtime:8.2.0 bash
astro@23baa05cdc14:/usr/local/airflow$ a = $(airflow variables get test)
Variable test does not exist
bash: a: command not found
astro@23baa05cdc14:/usr/local/airflow$ echo $a

astro@23baa05cdc14:/usr/local/airflow$

How to reproduce

Try fetching a variable using airflow cli with Runtime:8.2.0

Operating System

Debian GNU/Linux 11 (bullseye)

It doesn't look like a bug to me, you can get the output you want if you have spaces between the equal sign.
e.g b = $(airflow variables get test). This b=$(airflow variables get test) means setting environment variable

Thanks @ephraimbuddy for this. But shouldn't setting environment variable also not include logs?

Looks like it's just the way bash works. Closing the issue.
