Class RecoveredReplicationSource

java.lang.Object

org.apache.hadoop.hbase.replication.regionserver.ReplicationSource

org.apache.hadoop.hbase.replication.regionserver.RecoveredReplicationSource

All Implemented Interfaces:

ReplicationSourceInterface

@InterfaceAudience.Private
public class RecoveredReplicationSource
extends ReplicationSource

Class that handles the recovered source of a replication stream, which is transfered from another dead region server. This will be closed when all logs are pushed to peer cluster.

                 MetricsSource metrics)
          throws IOException

Description copied from class: ReplicationSource

Instantiation method used by region servers

Specified by:

init in interface ReplicationSourceInterface

Overrides:

init in class ReplicationSource

Parameters:

conf - configuration to use

fs - file system to use

manager - replication manager to ping to

server - the server for this region server

peerClusterZnode - the id of our replication queue

clusterId - unique UUID for the cluster

metrics - metrics for replication source

Throws:

IOException

createNewShipper

protected RecoveredReplicationSourceShipper createNewShipper(String walGroupId,
                                                             PriorityBlockingQueue<org.apache.hadoop.fs.Path> queue)

Overrides:

createNewShipper in class ReplicationSource

locateRecoveredPaths

public void locateRecoveredPaths(PriorityBlockingQueue<org.apache.hadoop.fs.Path> queue)
                          throws IOException

Throws:

IOException

getPeerId

public String getPeerId()

Description copied from interface: ReplicationSourceInterface

Get the id that the source is replicating to.

Specified by:

getPeerId in interface ReplicationSourceInterface

Overrides:

getPeerId in class ReplicationSource

Returns:

peer id

getServerWALsBelongTo

public org.apache.hadoop.hbase.ServerName getServerWALsBelongTo()

Description copied from interface: ReplicationSourceInterface

The queue of WALs only belong to one region server. This will return the server name which all WALs belong to.

Specified by:

getServerWALsBelongTo in interface ReplicationSourceInterface

Overrides:

getServerWALsBelongTo in class ReplicationSource

Returns:

the server name which all WALs belong to

isRecovered

public boolean isRecovered()

Returns:

whether this is a replication source for recovery.
