> Currently considerLoad avoids choosing nodes that are too active, so it helps
> level the HDFS load across the cluster. Under normal conditions, this is
> desired. However, when a cluster has a large percentage of nearly full nodes,
> this can make it difficult to find good targets because the placement policy
> wants to avoid the full nodes, but considerLoad wants to avoid the busy
> less-full nodes.
