方法详细资料

getId

String getId()

Get the identifier of this peer

返回:

string representation of the id

getPeerState

ReplicationPeer.PeerState getPeerState()

Returns the state of the peer by reading local cache.

返回:

the enabled state

isPeerEnabled

default boolean isPeerEnabled()

Test whether the peer is enabled.

返回:

true if enabled, otherwise false.

getPeerConfig

ReplicationPeerConfig getPeerConfig()

Get the peer config object

返回:

the ReplicationPeerConfig for this peer

getConfiguration

org.apache.hadoop.conf.Configuration getConfiguration()

Get the configuration object required to communicate with this peer

返回:

configuration object

getTableCFs

Map<TableName,List<String>> getTableCFs()

Get replicable (table, cf-list) map of this peer

返回:

the replicable (table, cf-list) map

getNamespaces

Set<String> getNamespaces()

Get replicable namespace set of this peer

返回:

the replicable namespaces set

getPeerBandwidth

long getPeerBandwidth()

Get the per node bandwidth upper limit for this peer

返回:

the bandwidth upper limit

registerPeerConfigListener

void registerPeerConfigListener(ReplicationPeerConfigListener listener)

Register a peer config listener to catch the peer config change event.

参数:

listener - listener to catch the peer config change event.

trackPeerConfigChanges

@Deprecated
default void trackPeerConfigChanges(ReplicationPeerConfigListener listener)

已过时。 Use registerPeerConfigListener(ReplicationPeerConfigListener) instead.
