public ReplicationPeerImpl(org.apache.hadoop.conf.Configuration conf,
                           String id,
                           ReplicationPeerConfig peerConfig,
                           boolean peerState,
                           SyncReplicationState syncReplicationState,
                           SyncReplicationState newSyncReplicationState)

Constructor that takes all the objects required to communicate with the specified peer, except for the region server addresses.

Parameters:

conf - configuration object to this peer

id - string representation of this peer's identifier

peerConfig - configuration for the replication peer

Method Detail

setPeerState

public void setPeerState(boolean enabled)

setPeerConfig

public void setPeerConfig(ReplicationPeerConfig peerConfig)

setNewSyncReplicationState

public void setNewSyncReplicationState(SyncReplicationState newState)

transitSyncReplicationState

public void transitSyncReplicationState()

getId

public String getId()

Get the identifier of this peer

Specified by:

getId in interface ReplicationPeer

Returns:

string representation of the id (short)

getPeerState

public ReplicationPeer.PeerState getPeerState()

Description copied from interface: ReplicationPeer

Returns the state of the peer by reading local cache.

Specified by:

getPeerState in interface ReplicationPeer

Returns:

the enabled state

getSyncReplicationStateAndNewState

getNamespaces

public Set<String> getNamespaces()

Description copied from interface: ReplicationPeer

Get replicable namespace set of this peer

Specified by:

getNamespaces in interface ReplicationPeer

Returns:

the replicable namespaces set

getPeerBandwidth

public long getPeerBandwidth()

Description copied from interface: ReplicationPeer
