PublishClusterStateAction

Method Detail

publish

public void publish(ClusterChangedEvent clusterChangedEvent,
                    int minMasterNodes,
                    ClusterStatePublisher.AckListener ackListener)
             throws FailedToCommitClusterStateException

publishes a cluster change event to other nodes. if at least minMasterNodes acknowledge the change it is committed and will be processed by the master and the other nodes.

The method is guaranteed to throw a FailedToCommitClusterStateException if the change is not committed and should be rejected. Any other exception signals the something wrong happened but the change is committed.

Throws:

FailedToCommitClusterStateException

serializeFullClusterState
