Sean Owen resolved SPARK-4475.
------------------------------
Resolution: Won't Fix
Target Version/s: (was: 1.1.1, 1.2.0, 1.0.3)
I think this could be reopened if there were follow up on the question on when
localhost would not resolve, which isn't a Spark issue per se, and an argument
that 127.0.0.1 were almost always better. There were arguments against that in
the PR.
> PySpark failed to initialize if localhost can not be resolved
