Description

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.
