by [~mingma], it seems like an incompatible change. We may have to put it
only in trunk.

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 2.8.0
> Reporter: Rushabh S Shah
> Assignee: Rushabh S Shah
>
> 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.
