Josh Rosen resolved SPARK-625.
------------------------------
Resolution: Fixed
Let's resolve this as "Fixed" for now. Reducing Akka's sensitivity to
hostnames is a more general issue and we may have a fix for this in the future
by either upgrading to a version of Akka that differentiates between bound and
advertised addressed or by replacing Akka with a different communications
layer. I don't think we've observed the "hang indefinitely" behavior described
in this ticket for many versions, so I think this should be safe to close.

> Key: SPARK-625
> URL: https://issues.apache.org/jira/browse/SPARK-625
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 0.7.0, 0.7.1, 0.8.0
> Reporter: Josh Rosen
> Priority: Minor
>
> I launched a standalone cluster on my laptop, connecting the workers to the
> master using my machine's public IP address (128.32.*.*:7077). If I try to
> connect spark-shell to the master using "spark://0.0.0.0:7077", it
> successfully brings up a Scala prompt but hangs when I try to run a job.
> From the standalone master's log, it looks like the client's messages are
> being dropped without the client discovering that the connection has failed:
> {code}
