Daniel Imberman commented on AIRFLOW-5447:
------------------------------------------
[~Yuval.Itzchakov] [~cwegrzyn]Thank you guys for getting this info to us. I
THINK this might have to do with a bug in the k8s kubernetes client which
requires "create" and "get" privileges for "pods/exec"
[https://stackoverflow.com/questions/53827345/airflow-k8s-operator-xcom-handshake-status-403-forbidden]
[https://github.com/kubernetes-client/python/issues/690]
The reason I believe this is that this lack of running/updating of pods point
to a failure or the KubernetesJobWatcher. When we finally started seeing
similar problems we were seeing these failures from the JobWatcherÂ

I'm going to look into this further tomorrow and get back ASAP.
> KubernetesExecutor hangs on task queueing
> -----------------------------------------
>
> Key: AIRFLOW-5447
> URL: https://issues.apache.org/jira/browse/AIRFLOW-5447
> Project: Apache Airflow
> Issue Type: Bug
> Components: executor-kubernetes
> Affects Versions: 1.10.4, 1.10.5
> Environment: Kubernetes version v1.14.3, Airflow version 1.10.4-1.10.5
> Reporter: Henry Cohen
> Assignee: Daniel Imberman
> Priority: Blocker
>
> Starting in 1.10.4, and continuing in 1.10.5, when using the
> KubernetesExecutor, with the webserver and scheduler running in the
> kubernetes cluster, tasks are scheduled, but when added to the task queue,
> the executor process hangs indefinitely. Based on log messages, it appears to
> be stuck at this line
