> [MR-279] NodeManager should start its servers on ephemeral ports
> -----------------------------------------------------------------
>
> Key: MAPREDUCE-2750
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2750
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.0
> Reporter: Vinod Kumar Vavilapalli
> Assignee: Anupam Seth
> Fix For: 0.23.0
>
>
> There is absolutely no need for NM to start ContainerManager on a standard
> port, it should bind to an ephemeral port. Binding on ephemeral ports will
> help us start multiple NMs on a single node without any issues.
> The same holds for the ResourceLocalizationService's server port and NM Http
> server's port.
