> Now with striped blocks and the design that uses a single BlockInfoStriped
> object to track all the corresponding blocks, we need to clearly distinguish
> the type Block and BlockInfo in BlockManager. Specifically, data structures
> like {{UnderReplicatedBlocks}} and {{PendingReplicationBlocks}} should track
> BlockInfo instead of Block in order to support striped block recovery.
