> Modify the assignment logic of dirFetchRequests variables
> ---------------------------------------------------------
>
> Key: SPARK-37029
> URL: https://issues.apache.org/jira/browse/SPARK-37029
> Project: Spark
> Issue Type: Improvement
> Components: Shuffle
> Affects Versions: 3.1.2, 3.2.0
> Reporter: jinhai
> Priority: Major
>
> In the ShuffleBlockFetcherIterator.fetchHostLocalBlocks method, we generate
> dirFetchRequests based on externalShuffleServiceEnabled. But in fact, the
> MapStatus object generated in the shuffle write phase had already generated
> the BlockManagerId object according to externalShuffleServiceEnabled in the
> BlockManager.initialize method.
> So we don't need to judge it again.
