applyClusterState

public void applyClusterState(ClusterChangedEvent event)

Description copied from interface: ClusterStateApplier

Called when a new cluster state (ClusterChangedEvent.state() needs to be applied. The cluster state to be applied is already committed when this method is called, so an applier must therefore be prepared to deal with any state it receives without throwing an exception. Throwing an exception from an applier is very bad because it will stop the application of this state before it has reached all the other appliers, and will likely result in another attempt to apply the same (or very similar) cluster state which might continue until this node is removed from the cluster.

Specified by:

applyClusterState in interface ClusterStateApplier
