---------------------------------
Summary: Remove use of ExecutionAttemptMappingProvider
Key: FLINK-31853
URL: https://issues.apache.org/jira/browse/FLINK-31853
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Affects Versions: 1.18.0
Reporter: Junrui Li
Fix For: 1.18.0
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.
