Jing Zhao commented on HDFS-4072:
---------------------------------
Thanks for the comment Eli! I think you're right: the
PendingReplicationBlocks#remove only decrements the pending replication number
by 1, it's not removing the whole record. So I guess we only need to remove the
whole record about the block from PendingReplicationBlocks here, and we can
still do this operation in BlockManager#removeBlock().
> When deleting a file, it would be better to also remove corresponding block
> records from BlockManager#pendingReplications
