**Apache Airflow version**: 1.10.13
**Environment**:
- **Cloud provider or hardware configuration**:AWS
- **OS** (e.g. from /etc/os-release): Amazon Linux 2
- **Kernel** (e.g. `uname -a`): 4.14.209-160.339.amzn2.x86_64
- **Install tools**: pip
- **Others**:
**What happened**:
When an ECS Task exits with `stopCode: TaskFailedToStart`, the ECS Operator
will exit with a ResourceNotFoundException for the GetLogEvents operation. This
is because the task has failed to start, so no log is created.

```
<!-- (please include exact error messages if you can) -->
**What you expected to happen**:
ResourceNotFoundException is misleading because it feels like a problem with
CloudWatchLogs. Expect AirflowException to indicate that the task has failed.
<!-- What do you think went wrong? -->
**How to reproduce it**:
<!---
As minimally and precisely as possible. Keep in mind we do not have access
to your cluster or dags.
If you are using kubernetes, please attempt to recreate the issue using
minikube or kind.
## Install minikube/kind
- Minikube https://minikube.sigs.k8s.io/docs/start/
- Kind https://kind.sigs.k8s.io/docs/user/quick-start/
If this is a UI bug, please provide a screenshot of the bug or a link to a
youtube video of the bug in action
You can include images using the .md style of
To record a screencast, mac users can use QuickTime and then create an
unlisted youtube video with the resulting .mov file.
--->
This can be reproduced by running an ECS Task that fails to start, for
example by specifying a non-existent entry_point.
**Anything else we need to know**:
<!--
How often does this problem occur? Once? Every time etc?
Any relevant logs to include? Put them here in side a detail tag:
<details><summary>x.log</summary> lots of stuff </details>
-->
I suspect Issue #11663 has the same problem, i.e. it's not a CloudWatch
issue, but a failure to start an ECS Task.
