[jira] [Created] (AIRFLOW-4515) KubernetesExecutor hangs in the subdag context

Steven Locke created AIRFLOW-4515:
-------------------------------------

             Summary: KubernetesExecutor hangs in the subdag context
                 Key: AIRFLOW-4515
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-4515
             Project: Apache Airflow
          Issue Type: Bug
          Components: kubernetes
    Affects Versions: 1.10.3
            Reporter: Steven Locke


The bug is that when using the kubernetes executor in a k8s cluster and running a subdag with `executor=KubernetesExecutor()` the subdag never returns. Just runs infinitely. Here is an example repo https://github.com/slocke716/test_subdags

This is occurring on 1.10.3 1.10.3post1 and 1.10.3b2 at least

Not passing `executor=KubernetesExecutor()` into the subdag operator is not an option since it defaults to the SequentialExecutor and changing to the LocalExecutor causes thread errors because we require quite a bit of concurrency
