      Description

      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.
