Describe the bug
During the Write Stage retry phase, the MapOutputTrackerMaster clears the MapStatus corresponding to the shuffleId on the Driver side. However, when a large number of partitions are encountered, the MapStatus may not be completely cleared. Retry at the Stage, the task becomes less, resulting in data loss. At present, I encountered a 40000 Partition, resulting in data loss.
