java.lang.Object

org.apache.hadoop.hbase.replication.regionserver.ReplicationSinkManager

@InterfaceAudience.Private
public class ReplicationSinkManager
extends Object

Maintains a collection of peers to replicate to, and randomly selects a single peer to replicate to per set of data to replicate. Also handles keeping track of peer availability.

ReplicationSinkManager

public ReplicationSinkManager(ClusterConnection conn,
                              String peerClusterId,
                              HBaseReplicationEndpoint endpoint,
                              org.apache.hadoop.conf.Configuration conf)

Instantiate for a single replication peer cluster.

参数:

conn - connection to the peer cluster

peerClusterId - identifier of the peer cluster

endpoint - replication endpoint for inter cluster replication

conf - HBase configuration, used for determining replication source ratio and bad peer threshold

方法详细资料

getReplicationSink

public ReplicationSinkManager.SinkPeer getReplicationSink()
                                                   throws IOException

Get a randomly-chosen replication sink to replicate to.

返回:

a replication sink to replicate to

抛出:

IOException

reportBadSink

public void reportBadSink(ReplicationSinkManager.SinkPeer sinkPeer)

Report a SinkPeer as being bad (i.e. an attempt to replicate to it failed). If a single SinkPeer is reported as bad more than replication.bad.sink.threshold times, it will be removed from the pool of potential replication targets.

参数:

sinkPeer - The SinkPeer that had a failed replication attempt on it

reportSinkSuccess

public void reportSinkSuccess(ReplicationSinkManager.SinkPeer sinkPeer)

Report that a SinkPeer successfully replicated a chunk of data.

参数:

sinkPeer - The SinkPeer that had a failed replication attempt on it

chooseSinks

public void chooseSinks()

Refresh the list of sinks.

getNumSinks

public int getNumSinks()

getSinksForTesting

protected List<ServerName> getSinksForTesting()
