Jing Zhao commented on HDFS-7912:
---------------------------------

Yeah, the block contained in the LocatedBlock {{lBlk}} here is actually a 
BlockInfo object since it is created by {{BlockManager#createLocatedBlock}}. 
But currently I do not see an easy way to avoid this extra {{getStoredBlock}} 
call. How about revisiting this when we update some other fsck code for 
supporting striped blocks?

> Erasure Coding: track BlockInfo instead of Block in UnderReplicatedBlocks and 
> PendingReplicationBlocks

> 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.
