> 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.
