      Description

      As we all know that spark on Yarn uses DB to record RegisteredExecutors information which can be reloaded and used again when the ExternalShuffleService is restarted .

      The RegisteredExecutors information can't be recorded both in the mode of spark's standalone and spark on k8s , which will cause the RegisteredExecutors information to be lost ,when the ExternalShuffleService is restarted.

      To solve the problem above, a method is proposed and is committed .
