> As discussed on HDFS-8872, we should mark a block as missing if all the 
> replicas on decommissioned nodes since we can take the decommissioned nodes 
> out of rotation anytime.
> We have seen multiple cases where all the replicas land on decommissioned 
> nodes.
> After HDFS-7933, it doesn't mark as missing.
