Class TcpDiscoveryStatusCheckMessage

java.lang.Object

org.apache.ignite.spi.discovery.tcp.messages.TcpDiscoveryAbstractMessage

org.apache.ignite.spi.discovery.tcp.messages.TcpDiscoveryStatusCheckMessage

All Implemented Interfaces:

Serializable

public class TcpDiscoveryStatusCheckMessage
extends TcpDiscoveryAbstractMessage

Message sent by node to its next to ensure that next node and connection to it are alive. Receiving node should send it across the ring, until message does not reach coordinator. Coordinator responds directly to node.

If a failed node id is specified then the message is sent across the ring up to the sender node to ensure that the failed node is actually failed.
