> Retry remote fileSegmentManagedBuffer when creating inputStream failed during shuffle read phase
> ------------------------------------------------------------------------------------------------
>
> Key: SPARK-26795
> URL: https://issues.apache.org/jira/browse/SPARK-26795
> 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.
