Package	Description
org.apache.hadoop.hbase.master
org.apache.hadoop.hbase.master.normalizer	The Region Normalizer subsystem is responsible for coaxing all the regions in a table toward a "normal" size, according to their storefile size.

Class and Description
MergeNormalizationPlan Normalization plan to merge adjacent regions.
MergeNormalizationPlan.Builder A helper for constructing instances of MergeNormalizationPlan.
NormalizationPlan A NormalizationPlan describes some modification to region split points as identified by an instance of RegionNormalizer.
NormalizationPlan.PlanType
NormalizationTarget A POJO that caries details about a region selected for normalization through the pipeline.
RegionNormalizer Performs "normalization" of regions of a table, making sure that suboptimal choice of split keys doesn't leave cluster in a situation when some regions are substantially larger than others for considerable amount of time.
RegionNormalizerChore Chore that will periodically call HMaster.normalizeRegions(NormalizeTableFilterParams, boolean).
RegionNormalizerManager This class encapsulates the details of the RegionNormalizer subsystem.
RegionNormalizerWorker Consumes normalization request targets (TableNames) off the RegionNormalizerWorkQueue, dispatches them to the RegionNormalizer, and executes the resulting NormalizationPlans.
RegionNormalizerWorkQueue A specialized collection that holds pending work for the RegionNormalizerWorker.
SimpleRegionNormalizer.NormalizeContext Inner class caries the state necessary to perform a single invocation of SimpleRegionNormalizer.computePlansForTable(TableDescriptor).
SimpleRegionNormalizer.NormalizerConfiguration Holds the configuration values read from Configuration.
SplitNormalizationPlan Normalization plan to split a region.
