com.hazelcast.spi.hotrestart.cluster

Class AskForClusterStartResultOperation

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.spi.hotrestart.cluster.AskForClusterStartResultOperation

All Implemented Interfaces:

com.hazelcast.internal.cluster.impl.operations.JoinOperation, com.hazelcast.nio.serialization.DataSerializable, com.hazelcast.nio.serialization.IdentifiedDataSerializable, com.hazelcast.spi.impl.AllowedDuringPassiveState, com.hazelcast.spi.UrgentSystemOperation

public class AskForClusterStartResultOperation
extends com.hazelcast.spi.Operation
implements com.hazelcast.internal.cluster.impl.operations.JoinOperation

It may happen that master can fail just after validating partition table of the nodes. If next master doesn't receive the status change and some of other nodes receive, next master can not validate partition tables since some of other nodes will not send their partition table as they started loading hot restart data. Master sends this operation to other nodes to check if there is a status change it missed.
