@InterfaceAudience.Private public class SimpleRegionNormalizer extends java.lang.Object implements RegionNormalizer
Region sizes are coarse and approximate on the order of megabytes. Additionally, "empty" regions (less than 1MB, with the previous note) are not merged away. This is by design to prevent normalization from undoing the pre-splitting of a table.
