Description

This JIRA aims to refactor the signatures fetchBlockByteRange and actualGetFromOneDataNode. Instead of taking a LocatedBlock, I think they should just take the starting offset of that block, since they'll later call getBlockAt to refresh the location anyway. I think we should make it clear so the callers are not surprised if the finally used LocatedBlock is not the one they passed in.
