Classes in org.apache.hadoop.hbase.master.balancer used by org.apache.hadoop.hbase.master.balancerClassDescriptionAn action to move or swap a regionAn efficient array based implementation similar to ClusterState for keeping the status of the cluster in terms of region assignment and distribution.Wrapper class for the few fields required by the
StochasticLoadBalancerfrom the fullRegionMetrics.The base class for load balancers.Generates a candidate action to be applied to the cluster for cost function searchClass used to hold the current state of the cluster and how balanced it is.Class to be used for the subset of RegionLoad costs that should be treated as rates.Base class the allows writing costs functions from rolling average of some number from RegionLoad.Base class of StochasticLoadBalancer's Cost Functions.A helper class to compute a scaled cost usingDescriptiveStatistics().Compute a cost of a potential cluster configuration based upon whereHStoreFiles are located.Faced for exposing metrics about the balancer.This metrics balancer uses extended source for stochastic load balancer to report its related metrics to JMX.This interface extends the basic metrics balancer source to add a function to report metrics that related to stochastic load balancer.The following comparator assumes that RegionId from HRegionInfo can represent the age of the region - larger RegionId means the region is younger.This will find where data for a region is located in HDFS.Generates candidates which moves the replicas out of the region server for co-hosted region replicasA cost function for region replicas.A cost function for region replicas.A cost function for region replicas for the rack distribution.Data structure that holds servername and 'load'.Stores additional per-server information about the regions added/removed during the run of the balancing algorithm.This is a best effort load balancer.
