 Question about bkill limitations with LSF Connector for Kubernetes

Hello, 

I’m currently working on integrating LSF Connector for Kubernetes, and I have a question.

According to the official documentation, under the section “Limitations with LSF Connector for Kubernetes,” it says that the bkill command is only partially supported.

I’m wondering exactly to what extent bkill is supported.

In my testing, when a job is submitted from Kubernetes, running bkill on the lsfmaster does not seem to work at all on those jobs.

Does anyone know specifically what is meant by “limited support” in the documentation? In what cases or under what conditions does bkill work with jobs submitted through the LSF Connector for Kubernetes?

I would really appreciate any insights you could share.

When I tried the bkill command, I got the following output:
Job <947>: Cannot perform the operation on Kubernetes control jobs

Here’s the link to the official documentation about the limitations:
