plockaby opened a new pull request #20147:
URL: https://github.com/apache/airflow/pull/20147
I did not have a chance to fix the previously hidden error about cleaning up
files when submitting #20114 before it was merged. When the temporary file's
ownership is changed for impersonation it can't be removed automatically by the
NamedTemporaryFile class so we need to manually remove it with sudo.
Basically, this is to fix this error message when a task finishes:
```
[2021-12-08 06:31:05,703: ERROR/ForkPoolWorker-31] Failed to execute task
[Errno 1] Operation not permitted: '/tmp/tmp9g_3zc5j'.
