Modifier and Type	Method and Description
List<RegionPlan>	LoadBalancer.balanceCluster(Map<TableName,Map<ServerName,List<RegionInfo>>> loadOfAllTable) Perform the major balance operation for cluster, will invoke LoadBalancer.balanceTable(org.apache.hadoop.hbase.TableName, java.util.Map<org.apache.hadoop.hbase.ServerName, java.util.List<org.apache.hadoop.hbase.client.RegionInfo>>) to do actual balance.
List<RegionPlan>	LoadBalancer.balanceTable(TableName tableName, Map<ServerName,List<RegionInfo>> loadOfOneTable) Perform the major balance operation for table, all class implement of LoadBalancer should override this method
List<RegionPlan>	HMaster.executeRegionPlansWithThrottling(List<RegionPlan> plans) Execute region plans with throttling
List<RegionPlan>	MasterServices.executeRegionPlansWithThrottling(List<RegionPlan> plans) Execute region plans with throttling

Modifier and Type	Method and Description
int	RegionPlan.RegionPlanComparator.compare(RegionPlan l, RegionPlan r)
int	RegionPlan.compareTo(RegionPlan other) Compare the region info.
private static int	RegionPlan.compareTo(RegionPlan left, RegionPlan right)

Method parameters in org.apache.hadoop.hbase.master with type arguments of type RegionPlan

Modifier and Type	Method and Description

Uses of RegionPlan in org.apache.hadoop.hbase.master.balancer

Methods in org.apache.hadoop.hbase.master.balancer that return types with arguments of type RegionPlan

Modifier and Type	Method and Description
List<RegionPlan>	SimpleLoadBalancer.balanceCluster(Map<TableName,Map<ServerName,List<RegionInfo>>> loadOfAllTable) Override to invoke SimpleLoadBalancer.setClusterLoad(java.util.Map<org.apache.hadoop.hbase.TableName, java.util.Map<org.apache.hadoop.hbase.ServerName, java.util.List<org.apache.hadoop.hbase.client.RegionInfo>>>) before balance, We need clusterLoad of all regions on every server to achieve overall balanced
List<RegionPlan>	BaseLoadBalancer.balanceCluster(Map<TableName,Map<ServerName,List<RegionInfo>>> loadOfAllTable)
protected List<RegionPlan>	BaseLoadBalancer.balanceMasterRegions(Map<ServerName,List<RegionInfo>> clusterMap) Balance the regions that should be on master regionserver.
List<RegionPlan>	StochasticLoadBalancer.balanceTable(TableName tableName, Map<ServerName,List<RegionInfo>> loadOfOneTable) Given the cluster state this will try and approach an optimal balance.
List<RegionPlan>	SimpleLoadBalancer.balanceTable(TableName tableName, Map<ServerName,List<RegionInfo>> loadOfOneTable) Generate a global load balancing plan according to the specified map of server information to the most loaded regions of each server.
List<RegionPlan>	FavoredStochasticBalancer.balanceTable(TableName tableName, Map<ServerName,List<RegionInfo>> loadOfOneTable)
abstract List<RegionPlan>	BaseLoadBalancer.balanceTable(TableName tableName, Map<ServerName,List<RegionInfo>> loadOfOneTable)
private List<RegionPlan>	StochasticLoadBalancer.createRegionPlans(BaseLoadBalancer.Cluster cluster) Create all of the RegionPlan's needed to move from the initial cluster state to the desired state.

Method parameters in org.apache.hadoop.hbase.master.balancer with type arguments of type RegionPlan

Modifier and Type	Method and Description
private void	SimpleLoadBalancer.addRegionPlan(org.apache.hbase.thirdparty.com.google.common.collect.MinMaxPriorityQueue<RegionPlan> regionsToMove, boolean fetchFromTail, ServerName sn, List<RegionPlan> regionsToReturn) Add a region from the head or tail to the List of regions to return.
private void	SimpleLoadBalancer.addRegionPlan(org.apache.hbase.thirdparty.com.google.common.collect.MinMaxPriorityQueue<RegionPlan> regionsToMove, boolean fetchFromTail, ServerName sn, List<RegionPlan> regionsToReturn) Add a region from the head or tail to the List of regions to return.
