[druid-user] Kubernetes + HDFS Deep Storage Deployment Issues

We’re trying to deploy Apache Druid on Kubernetes and use an existing HDFS cluster on the K8s cluster as the deep storage solution. We’re running into trouble trying to figure out how to get the core-site.xml and hdfs-site.xml config files in the ${DRUID_HOME}/conf/_common directory for the pods. We’ve tried mounting ConfigMaps with the files and this appears to conflict with both the Helm chart and Kubernetes Operator. Neither appear to have ways to natively include these files required by the druid-hdfs-storage extension.

Any advice would be greatly appreciated.

Thank you!
