> Currently, the ExecutionAttemptMappingProvider class used to map
> ExecutionAttemptID to ExecutionVertex, which is only used when reporting
> checkpoint statistics in checkpointCoordinator. However, after Flink-17295,
> we refactored ExecutionAttemptID to consist of executionGraphId,
> executionVertexId, and attemptNumber. Therefore, the
> ExecutionAttemptMappingProvider class can be removed.
