             Summary: Refactor block mapping by reusing blockInfoWrappers for better block management
                 Key: SPARK-54947
                 URL: https://issues.apache.org/jira/browse/SPARK-54947
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 4.2.0
            Reporter: wuyi


SPARK-53446 has optimized block seraching by the additional block mapping between the main blockId and the block pieces. It's a great idea that speeds up the block searching. And we could optimize it by resusing the existing blockInfoWrappers rather than three new HashMaps for better block management.
