Description

Lost nodemanagers fail to join back.

When the NM is lost, RM log reads

INFO org.apache.hadoop.yarn.util.AbstractLivelinessMonitor: Expired:<host:port> Timed out after 600 secs
INFO org.apache.hadoop.yarn.server.resourcemanager.rmnode.RMNodeImpl: Processing <host:port> of type EXPIRE
INFO org.apache.hadoop.yarn.server.resourcemanager.rmnode.RMNodeImpl: Removed Node <host:port>
INFO org.apache.hadoop.yarn.server.resourcemanager.rmnode.RMNodeImpl: <host:port> Node Transitioned from RUNNING to LOST

When the NM joins back, RM log reads

INFO org.apache.hadoop.yarn.server.resourcemanager.ResourceTrackerService: Node not found rebooting <host:port>
