Description
When pacemaker goes down, all the heartbeats of workers are lost. These heartbeats will need a long time to recover even if pacemaker goes up immediately if it costs dozens of GB memory. During the time worker heartbeats are not complete，Nimbus will think the workers are died( heartbeat time out ), and reassign these workers crazily. But actually the workers are healthy, the reassignment will move in cycles until pacemaker heartbeats recover. During this time, all the topologies's throughout will goes down. We should avoid this, because Pacemaker has no HA.
