Subject [jira] [Resolved] (SPARK-4389) Set akka.remote.netty.tcp.bind-hostname="0.0.0.0" so driver can be located behind NAT
Date Wed, 16 Sep 2015 18:56:47 GMT

     [ https://issues.apache.org/jira/browse/SPARK-4389?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Josh Rosen resolved SPARK-4389.
-------------------------------
    Resolution: Won't Fix

I'm going to resolve this as "Won't Fix":

- Akka 2.4 has not shipped yet, so this feature isn't supported in any released version.
- Akka 2.4 requires Java 8 and Scala 2.11 or 2.12, meaning that we can't use it in Spark as
long as we need to continue to support Java 7 and Scala 2.10. We'll replace Akka RPC with
a custom RPC layer long before we'll be able to drop support for these platforms.

>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core
>    Affects Versions: 1.2.0
>            Reporter: Josh Rosen
>            Priority: Minor
>
> We should set {{akka.remote.netty.tcp.bind-hostname="0.0.0.0"}} in our Akka configuration
so that Spark drivers can be located behind NATs / work with weird DNS setups.
> This is blocked by upgrading our Akka version, since this configuration is not present
Akka 2.3.4.  There might be a different approach / workaround that works on our current Akka
version, though.
> EDIT: this is blocked by Akka 2.4, since this feature is only available in the 2.4 snapshot
release.
