RyanSiu1995 opened a new issue #8780:
URL: https://github.com/apache/airflow/issues/8780
**Apache Airflow version**: 1.10.10
**Kubernetes version (if you are using kubernetes)** (use `kubectl
version`):
```
> kubectl version
Client Version: version.Info{Major:"1", Minor:"14", GitVersion:"v1.14.7",
GitCommit:"8fca2ec50a6133511b771a11559e24191b1aa2b4", GitTreeState:"clean",
BuildDate:"2019-09-18T14:47:22Z", GoVersion:"go1.12.9", Compiler:"gc",
Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"14+",
GitVersion:"v1.14.10-gke.27",
GitCommit:"145f9e21a4515947d6fb10819e5a336aff1b6959", GitTreeState:"clean",
BuildDate:"2020-02-21T18:01:40Z", GoVersion:"go1.12.12b4", Compiler:"gc",
Platform:"linux/amd64"}
```
**Environment**:
- GKE
- Linux
- `Linux pod-name-597d575d8-xrmkn 4.14.138+ #1 SMP Tue Sep 3 02:58:08 PDT
2019 x86_64 GNU/Linu`
- `pip install`
**What happened**:
We used Kubernetes executor to execute our pipeline with a GCS remote log
storage. We encountered the log was not found in the GCS bucket for some DAGs.
It shares the same error like this.
```
*** Unable to read remote log from
gs://xxxx/zzz_test_on_hold/on_hold/2020-05-08T07:06:18.991443+00:00/1.log
*** 404 GET
https://storage.googleapis.com/download/storage/v1/b/xxxx/o/zzz_test_on_hold%2Fon_hold%2F2020-05-08T07%3A06%3A18.991443%2B00%3A00%2F1.log?alt=media:
('Request failed with status code', 404, 'Expected one of', <HTTPStatus.OK:
200>, <HTTPStatus.PARTIAL_CONTENT: 206>)
```
And we have gone into the log on stdout and found that there was error like
this.
```
Please make sure that airflow[gcp] is installed and the GCS connection
exists.
Could not write logs to
gs://xxxx/zzz_test_on_hold/on_hold/2020-05-08T07:06:18.991443+00:00/1.log:
'NoneType' object has no attribute 'upload'
```
**What you expected to happen**:
I expected the logs can still upload to GCS if the pod was unexpectedly
killed by Kubernetes.
**How to reproduce it**:
Write a DAG with the following function.
```python
def on_hold():
"""On hold the process"""
while True:
logger.warn("this is on holding now...")
time.sleep(1000)
```
When the task pod is spawned, kill the pod with kubectl.
The log then will not be able to be uploaded.
**Anything else we need to know**:
Nope
