zx10r resolved FLINK-23548.
---------------------------
Release Note: Resolved by attaching PVC volume and outputting logs there in
detached mode.
Resolution: Not A Bug
> Flink Session Cluster (Standalone) in Kubernetes: Exception occurred in REST
> handler: Could not execute application.
> --------------------------------------------------------------------------------------------------------------------
>
> Key: FLINK-23548
> URL: https://issues.apache.org/jira/browse/FLINK-23548
> Project: Flink
> Issue Type: Bug
> Affects Versions: 1.13.0, 1.13.1
> Reporter: zx10r
> Priority: Major
> Labels: Kubernetes
>
> Following the guide located here:
> [https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/deployment/resource-providers/standalone/kubernetes/]
> to deploy Session Cluster in standalone mode on Kubernetes seems to produce
> weird REST errors in the UI. When running any of the examples through the UI
> and submitting jobs the Job Manager will show: *Exception occurred in REST
> handler: Could not execute application* while the UI produces the bellow
> stack trace.
> I will mention the the job completes successfully and submitting the job
> through command line also works correctly but we are attempting to figure out
> why the UI/REST errors are appearing and if there is a possible fix in the
> kubernetes yaml definitions that are provided in the guide above. This is
> painful for us due to many of our users submitting jobs through the UI.
