-----------------------------------
Summary: Multiple app IDs could be generated for the same app
Key: YUNIKORN-589
URL: https://issues.apache.org/jira/browse/YUNIKORN-589
Project: Apache YuniKorn
Issue Type: Bug
Components: shim - kubernetes
Affects Versions: 0.10
Reporter: Chaoran Yu
Attachments: Screen Shot 2021-03-21 at 9.11.04 AM.png
When multiple app management plugins are enabled (e.g. general and spark
operator plugins), each plugin will generate its own app ID for the same app.
This alone may not be a problem, but when viewing app states in the UI, it can
get confusing, especially when two plugins have different opinions regarding
the current state of the same application. We probably need to introduce a
mechanism to optionally indicate whether a plugin is exclusive or not. If yes,
then a plugin will prevent other plugins from acting on the same app.
In the attached screenshot, both app IDs are for the same Spark job, the first
generated by the Spark operator plugin, the second by the general plugin. The
true state is that the app has completed, as indicated by the operator. But the
general plugin has no idea, as expected. In this case, we should just show the
first row.
Maybe this is mostly just a UI issue. But in the k8s shim, we also need a way
to tell that they are the same thing.
