> In Node manager log during startup the following logs is printed
> 2015-05-12 11:20:02,347 INFO org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl:
Initialized nodemanager for *null* : physical-memory=4096 virtual-memory=8602 virtual-cores=8
> This line is printed from NodeStatusUpdaterImpl.serviceInit.
> But the nodeid assignment is happening only in NodeStatusUpdaterImpl.serviceStart
> {code}
>   protected void serviceStart() throws Exception {
>     // NodeManager is the last service to start, so NodeId is available.
>     this.nodeId = this.context.getNodeId();
> {code}
> Assigning the node id in serviceinit is not feasible since it is generated by  ContainerManagerImpl.serviceStart.
> The log can be moved to service start to give right information to user.
