> MR AppMaster does not honor ephemeral port range
> ------------------------------------------------
>
> Key: MAPREDUCE-6338
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6338
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mr-am, mrv2
> Affects Versions: 2.6.0
> Reporter: Frank Nguyen
> Assignee: Frank Nguyen
> Attachments: MAPREDUCE-6338.001.patch
>
>
> The MR AppMaster should only use port ranges defined in the
> yarn.app.mapreduce.am.job.client.port-range property. On initial startup of
> the MRAppMaster, it does use the port range defined in the property.
> However, it also opens up a listener on a random ephemeral port. This is not
> the Jetty listener. It is another listener opened by the MRAppMaster via
> another thread and is recognized by the RM. Other nodes will try to
> communicate to it via that random port. With firewall settings on, the MR
> job will fail because the random port is not opened. This problem has caused
> others to have all OS ephemeral ports opened to have MR jobs run.
> This is related to MAPREDUCE-4079
