> When we run balancer with `BalancingPolicy.Node` policy, our goal is to make
> each datanode storage balanced. But in the current implementation, the
> balancer doesn't account for storage used by non-dfs on the datanodes, which
> can make the situation worse for datanodes that are already strained on
> storage.
