**Note:** If you do not specify a threshold, then a default value of 20 is used. If the balancer detects that a DataNode is using less than a 20% difference of the cluster's overall disk usage, then data on that node will not be rebalanced. For example, if disk usage across all DataNodes in the cluster is 40% of the cluster's total disk-storage capacity, then the balancer script ensures that a DataNode's disk usage is between 20% and 60% of that DataNode's disk-storage capacity. DataNodes whose disk usage falls within that percentage range will not be rebalanced.
