Method Detail

setAllocationService

public void setAllocationService(AllocationService allocationService)

Description copied from interface: Discovery

Another hack to solve dep injection problem..., note, this will be called before any start is called.

Specified by:

setAllocationService in interface Discovery

doStart

protected void doStart()

Specified by:

doStart in class AbstractLifecycleComponent

startInitialJoin

public void startInitialJoin()

Description copied from interface: Discovery

Triggers the first join cycle

Specified by:

startInitialJoin in interface Discovery

doStop

protected void doStop()

Specified by:

doStop in class AbstractLifecycleComponent

doClose

protected void doClose()

Specified by:

doClose in class AbstractLifecycleComponent

localNode

public DiscoveryNode localNode()

Specified by:

localNode in interface Discovery

nodeDescription

public java.lang.String nodeDescription()

Specified by:

nodeDescription in interface Discovery

publish

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

Description copied from interface: Discovery

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 keep track of the ack received from nodes, and verify whether they updated their own cluster state or not. The method is guaranteed to throw a Discovery.FailedToCommitClusterStateException if the change is not committed and should be rejected. Any other exception signals the something wrong happened but the change is committed.

Specified by:

publish in interface Discovery

stats

public DiscoveryStats stats()

Specified by:

stats in interface Discovery

Returns:

stats about the discovery

getDiscoverySettings

public DiscoverySettings getDiscoverySettings()

Specified by:

getDiscoverySettings in interface Discovery

getMinimumMasterNodes

public int getMinimumMasterNodes()

Specified by:

getMinimumMasterNodes in interface Discovery

Returns:

the current value of minimum master nodes, or -1 for not set
