> Key: MAPREDUCE-6739
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6739
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: mr-am
> Affects Versions: 2.7.2
> Reporter: Haibo Chen
> Assignee: Haibo Chen
> Labels: supportability
>
> 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.
