Description

Certain workloads submit further pods from within the cluster.

For example, the driver pod startved by spark-submit belongs to the user who authenticated externally. Subsequent executor pods, however, will be started by the driver pod from a service account which is defined in the command line.

In order to properly track resource usage, we need to check if there is OwnerReference set for a given pod. If it is, then we need to look up the existing pod/application and replace the user and group info. This also ensures that placeholders are handled properly, too.
