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

The provided solution is wrong because it is inconsistent with the rest of 
Spark. 

In every other place, when we want to refer to bind address, we should use 
{{Utils.localHostname}} 
(https://github.com/apache/spark/blob/branch-2.0/core/src/main/scala/org/apache/spark/util/Utils.scala#L895)
 so that when people want to set it programmatically they are able to do that 
(https://github.com/apache/spark/blob/branch-2.0/core/src/main/scala/org/apache/spark/util/Utils.scala#L886).

Another issue is that people do not always want to bind WebUI to the same 
interface as Spark internal communication. 

I think there should be another environment variable for binding web interface 
with fallback to {{Utils.localHostname}}.
