RetryingBlockTransferor

class RetryingBlockTransferor extends AnyRef

Wraps another BlockFetcher or BlockPusher with the ability to automatically retry block transfers which fail due to IOExceptions, which we hope are due to transient network conditions.

This transferor provides stronger guarantees regarding the parent BlockTransferListener. In particular, the listener will be invoked exactly once per blockId, with a success or failure.
