> If a block in a block group is reported by Datanode to Namenode, Namenode
> will check if it's corrupt. Currently {{BlockManager}} uses the size of block
> group to compare with the size of reported block, which makes the block is
> treated as corrupt block by Namenode. I think Namenode should first
> calculate the size of the block and then compare it with reported value
