[jira] [Created] (MAPREDUCE-2750) [MR-279] NodeManager should start
its servers on ephemeral ports
[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
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.
