BlockTransferMessage

abstract class BlockTransferMessage extends Encodable

Messages handled by the ExternalBlockHandler, or by Spark's NettyBlockTransferService.

At a high level:

  • OpenBlock is logically only handled by the NettyBlockTransferService, but for the capability for old version Spark, we still keep it in external shuffle service. It returns a StreamHandle.
  • UploadBlock is only handled by the NettyBlockTransferService.
  • RegisterExecutor is only handled by the external shuffle service.
  • RemoveBlocks is only handled by the external shuffle service.
  • FetchShuffleBlocks is handled by both services for shuffle files. It returns a StreamHandle.
