----------------------------
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.
