----------------------------------------
Summary: Watch configmap only in yunikorn's deployed namespace
Key: YUNIKORN-2850
URL: https://issues.apache.org/jira/browse/YUNIKORN-2850
Project: Apache YuniKorn
Issue Type: Improvement
Components: shim - kubernetes
Reporter: Tae-kyeom, Kim
Currently, Yunikorn uses configmap informer to handle configuration hot reload.
However, In current implementation informer watches all namespaces even only
need to watch namespace in which yunikorn is deployed. It causes in efficient
behavior when sync and cache configmap states. If there is too many unrelated
configmap in other namespace cause long recovery time to list and memory
presure to handle configmap caches.
So, If we could replace configmap informer to namespace restricted one, it
would improve startup / recovery time and reduce memory usage
