-------------------------------------

             Summary: allow specifying range on the port that MR AM web server binds to
                 Key: MAPREDUCE-6739
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6739
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Haibo Chen
            Assignee: Haibo Chen


MR AM web server binds itself to an arbitrary port.  This means if the RM web proxy lives
outside of a cluster, the whole port range needs to be wide open. It'd be nice to reuse yarn.app.mapreduce.am.job.client.port-range
to place a port range restriction on MR AM web server, so that connection from outside the
cluster can be restricted within a range of ports.
