Method Detail

getNoMasterBlock

public ClusterBlock getNoMasterBlock()

doStart

protected void doStart()

Specified by:

doStart in class AbstractLifecycleComponent<DiscoveryService>

joinClusterAndWaitForInitialState

public void joinClusterAndWaitForInitialState()

doStop

protected void doStop()

Specified by:

doStop in class AbstractLifecycleComponent<DiscoveryService>

doClose

protected void doClose()

Specified by:

localNode

public DiscoveryNode localNode()

nodeDescription

public String nodeDescription()

publish

public void publish(ClusterChangedEvent clusterChangedEvent,
           Discovery.AckListener ackListener)

Publish all the changes to the cluster from the master (can be called just by the master). The publish process should not publish this state to the master as well! (the master is sending it...).

The Discovery.AckListener allows to acknowledge the publish event based on the response gotten from all nodes

generateNodeId

public static String generateNodeId(Settings settings)
