> A datanode can't be decommissioned if it has replica that belongs to a file with a replication
factor larger than the rest of the cluster size.
> One way to fix this is to have some kind of minimum replication factor setting and thus
any datanode can be decommissioned regardless of the largest replication factor it's related
to.
