to print information for favored nodesView and edit the current cluster schema.Class to hold dead servers list and utility querying dead server list.HMaster is the "master server" for HBase.Makes decisions about the placement and movement of Regions across RegionServers.Provides the coprocessor framework and environment for master oriented operations.This class abstracts a bunch of operations the HMaster needs to interact with the underlying file system like creating the initial layout, checking file system status, etc.Implements the master RPC services.A curated subset of services provided byHMaster
.A state storage which stores the state in master local region.This class abstracts a bunch of operations the HMaster needs when splitting log files e.g.This class is for maintaining the various master statistics and publishing them through the metrics interfaces.Interface that classes that expose metrics about the master will implement.Interface of a factory to create MetricsMasterSource when given a MetricsMasterWrapperA collection of exposed metrics for space quotas from the HBase Master.Interface of a factory to create MetricsMasterQuotaSource when given a MetricsMasterWrapper.Interface that classes that expose metrics about the master will implement.Interface of a factory to create MetricsMasterSource when given a MetricsMasterWrapperThis is the interface that will expose information to hadoop1/hadoop2 implementations of the MetricsMasterSource.Stores the plan for the move of an individual region.For storing the region server list.State of a Region while undergoing transitions.Get notification of server registration events.The ServerManager class manages info about region servers.Used internally for reading meta and constructing datastructures that are then queried, for things like regions to regionservers, table to regions, etc.Deprecated.Deprecated.Keeps track of the batch of tasks submitted together by a caller in splitLogDistributed().Deprecated.Tracks the switch of split and merge states.CreateSplitWALProcedure
