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

["David Lum (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AIRFLOW-4515?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16903920#comment-16903920 ] 

David Lum commented on AIRFLOW-4515:
------------------------------------

Yeah unfortunately this looks like an inconsistency in the the way Executors are passed. You should be passing a dict with a key of 'KubernetesExecutor' and the value is another dict full of configuration parameters. I believe this ticket can be closed.

> 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
