>             Project: Spark
>          Issue Type: Bug
>          Components: Shuffle
>    Affects Versions: 2.3.0, 2.3.1, 2.3.2, 2.4.0
>            Reporter: feiwang
>            Priority: Major

> There is a parameter spark.maxRemoteBlockSizeFetchToMem, which means the remote block will be fetched to disk when size of the block is above this threshold in bytes.
> So during shuffle read phase, the managedBuffer which throw IOException may be a remote downloaded FileSegment and should be retried instead of throwFetchFailed directly.
