---------------------------------------
Hi Andrew!
You are right, I checked it, and I see that: with ip_local_reserved_ports
param, its possible to define comma separated port ranges, that should be a
better solution.

> When Ambari agent starts,it tries to use an ephemeral port that is already in
> use by another component.

> Solution:
> Range of ephemeral ports used by Ambari should be narrowed. (configurable)
