> Hadoop ignores yarn.nodemanager.hostname for RPC listeners

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: client, task
>    Affects Versions: 2.2.1, 2.4.1, 2.5.1
>         Environment: Any mapreduce example with standard cluster.  In our 
> case each node has four networks.  It is important that all internode 
> communication be done on a specific network.
>            Reporter: Waldyn Benbenek
>            Assignee: Waldyn Benbenek
>             Fix For: 2.5.1

> The RPC listeners for an application are using the hostname of the node as 
> the binding address of the listener,  They ignore yarn.nodemanager.hostname 
> for this.  In our setup we want all communication between nodes to be done 
> via the network addresses we specify in yarn.nodemanager.hostname on each 
> node.  
> TaskAttemptListenerImpl.java and MRClientService.java are two places I have 
> found where the default address is used rather that NM_host.   The node 
> Manager hostname should be used for all communication between nodes including 
> the RPC listeners.
