---------------------------------------------------------------

In RegionMXBean, there are examples of metrics that return -1 (int) or -1.0 (float) under scenarios when the value is not applicable. In one such example, getPutLocalRate() returns ManagementConstants.NOT_AVAILABLE_FLOAT when the region is not a partitioned region . I think we could do the same thing here when the operator does not specify directory sizes.
