Till Rohrmann commented on FLINK-12075:
---------------------------------------

I agree that we should fix this problem for the {{1.8.0}} release. I suggest 
the following as a solution: 

1. only set the Yarn bind-port to {{0}} if it has not been specified 
({{rest.bind-port}} and all of its fallback keys have not been set).
2. Remove the explicit setting of {{rest.port}} from the default config

That way, it should be possible to define a port range for {{rest.bind-port}} 
and keep the behaviour that you only need to specify a single option 
{{rest.port}} if you want to bind and connect to a single port which existing 
setups might depend on. Moreover, with 2. the Yarn case should work out of the 
box with random port binding.

>          Issue Type: Bug
>          Components: Deployment / YARN
>    Affects Versions: 1.7.2, 1.8.0
>            Reporter: Richard Deurwaarder
>            Priority: Blocker
>             Fix For: 1.8.0

> If there is a firewall around the YARN cluster and the machine, submitting 
> flink job it is unpractical because new flink clusters start up with random 
> ports for REST communication.
>  
> FLINK-5758 should've fixed this. But it seems FLINK-11081 either undid the 
> changes or did not implement this. The relevant code is changed in 
> FLINK-11081
