Interface Summary

Interface	Description
MetricsReplicationSinkSource
MetricsReplicationSource	Provides access to gauges and counters.
MetricsReplicationSourceFactory
MetricsReplicationSourceSource
PeerProcedureHandler	A handler for modifying replication peer in peer procedures.
ReplicationSourceInterface	Interface that defines a replication source
ReplicationSourceManager.ReplicationQueueOperation
SourceFSConfigurationProvider	Interface that defines how a region server in peer cluster will get source cluster file system configurations.
WALEntrySinkFilter	Implementations are installed on a Replication Sink called from inside ReplicationSink#replicateEntries to filter replicated WALEntries based off WALEntry attributes.
WALFileLengthProvider	Used by replication to prevent replicating unacked log entries.

Class Summary

Class	Description
DefaultSourceFSConfigurationProvider	This will load all the xml configuration files for the source cluster replication ID from user configured replication configuration directory.
DumpReplicationQueues	Provides information about the existing states of replication, replication peers and queues.
DumpReplicationQueues.DumpOptions
DumpReplicationQueues.WarnOnlyAbortable
DumpReplicationQueues.WarnOnlyStoppable
HBaseInterClusterReplicationEndpoint	A ReplicationEndpoint implementation for replicating to another HBase cluster.
HFileReplicator	It is used for replicating HFile entries.
MetricsReplicationGlobalSourceSource
MetricsReplicationSinkSourceImpl
MetricsReplicationSourceFactoryImpl
MetricsReplicationSourceImpl	Hadoop2 implementation of MetricsReplicationSource.
MetricsReplicationSourceSourceImpl
MetricsSink	This class is for maintaining the various replication statistics for a sink and publishing them through the metrics interfaces.
MetricsSource	This class is for maintaining the various replication statistics for a source and publishing them through the metrics interfaces.
PeerProcedureHandlerImpl
RecoveredReplicationSource	Class that handles the recovered source of a replication stream, which is transfered from another dead region server.
RecoveredReplicationSourceShipper	Used by a RecoveredReplicationSource.
RefreshPeerCallable	The callable executed at RS side to refresh the peer config/state.
RegionReplicaReplicationEndpoint	A ReplicationEndpoint endpoint which receives the WAL edits from the WAL, and sends the edits to replicas of regions.
RegionReplicaReplicationEndpoint.RegionReplicaOutputSink
RegionReplicaReplicationEndpoint.RegionReplicaReplayCallable	Calls replay on the passed edits for the given set of entries belonging to the region.
RegionReplicaReplicationEndpoint.RegionReplicaSinkWriter
RegionReplicaReplicationEndpoint.RetryingRpcCallable<V>
Replication	Gateway to Replication.
Replication.ReplicationStatisticsTask	Statistics task.
ReplicationLoad	This class is used for exporting some of the info from replication metrics
ReplicationObserver	An Observer to add HFile References to replication queue.
ReplicationSink	This class is responsible for replicating the edits coming from another cluster.
ReplicationSinkManager	Maintains a collection of peers to replicate to, and randomly selects a single peer to replicate to per set of data to replicate.
ReplicationSinkManager.SinkPeer	Wraps a replication region server sink to provide the ability to identify it.
ReplicationSource	Class that handles the source of a replication stream.
ReplicationSource.LogsComparator	Comparator used to compare logs together based on their start time
ReplicationSourceFactory	Constructs a ReplicationSourceInterface
ReplicationSourceManager	This class is responsible to manage all the replication sources.
ReplicationSourceShipper	This thread reads entries from a queue and ships them.
ReplicationSourceWALActionListener	Used to receive new wals.
ReplicationSourceWALReader	Reads and filters WAL entries, groups the filtered entries into batches, and puts the batches onto a queue
ReplicationStatus
ReplicationStatus.ReplicationStatusBuilder
ReplicationSyncUp	In a scenario of Replication based Disaster/Recovery, when hbase Master-Cluster crashes, this tool is used to sync-up the delta from Master to Slave using the info from ZooKeeper.
ReplicationThrottler	Per-peer per-node throttling controller for replication: enabled if bandwidth > 0, a cycle = 100ms, by throttling we guarantee data pushed to peer within each cycle won't exceed 'bandwidth' bytes
SerialReplicationChecker	Helper class to determine whether we can push a given WAL entry without breaking the replication order.
SerialReplicationSourceWALReader	WAL reader for a serial replication peer.
SwitchRpcThrottleRemoteCallable	The callable executed at RS side to switch rpc throttle state.
WALEntryBatch	Holds a batch of WAL entries to replicate, along with some statistics
WALEntryStream	Streaming access to WAL entries.

Exception Summary

Exception	Description
ReplicationRuntimeException	This exception is thrown when a replication source is terminated and source threads got interrupted.
