**Apache Airflow version**: 2.0.1

**Kubernetes version (if you are using kubernetes)** (use `kubectl version`): not used

**Environment**: Mac os(Catalina)

- **Cloud provider or hardware configuration**:
- **OS** (e.g. from /etc/os-release): Mac os(Catalina)
- **Kernel** (e.g. `uname -a`): `Darwin AL01590440.local 19.6.0 Darwin Kernel Version 19.6.0: Mon Aug 31 22:12:52 PDT 2020; root:xnu-6153.141.2~1/RELEASE_X86_64 x86_64`
- **Install tools**: pyenv, pip
- **Others**: python 3.6.13

**What happened**:
Example task of externaltasksensor doesn't work.
`example_external_task_marker_child` is never success even I tried `example_external_task_marker_parent` at the same time.
And finally, `example_external_task_marker_child` become failed due to timeout.

**How to reproduce it**:
- install python 3.6.13 using pyenv
- install latest airflow(2.0.1)
- setup db(default, maybe sqlite?), and add user, start scheduler, and run webserver
- trigger `example_external_task_marker_child` and `example_external_task_marker_parent` at the same time,
- Also tried `example_external_task_marker_parent` and `example_external_task_marker_child` but it shows same situation.
