Examples with ForwardMessageToBehaviorActor org.opendaylight.controller.cluster.raft.utils.ForwardMessageToBehaviorActor used on opensource projects

Example 1 with ForwardMessageToBehaviorActor

use of org.opendaylight.controller.cluster.raft.utils.ForwardMessageToBehaviorActor in project controller by opendaylight.

the class AbstractLeaderTest method testLeaderSchedulesHeartbeatsEvenWhenNoFollowersRespondToInitialAppendEntries.

/**
 * When we removed scheduling of heartbeat in the AbstractLeader constructor we ended up with a situation where
 * if no follower responded to an initial AppendEntries heartbeats would not be sent to it. This test verifies
 * that regardless of whether followers respond or not we schedule heartbeats.
