No, same result. I tried including my hostname in /etc/hosts which got me
past the above exception. However, now I get

> Create a general purpose framework for language bindings
> --------------------------------------------------------
>
> Key: FLINK-377
> URL: https://issues.apache.org/jira/browse/FLINK-377
> Project: Flink
> Issue Type: Improvement
> Reporter: GitHub Import
> Assignee: Chesnay Schepler
> Labels: github-import
> Fix For: pre-apache
>
>
> A general purpose API to run operators with arbitrary binaries.
> This will allow to run Stratosphere programs written in Python, JavaScript,
> Ruby, Go or whatever you like.
> We suggest using Google Protocol Buffers for data serialization. This is the
> list of languages that currently support ProtoBuf:
> https://code.google.com/p/protobuf/wiki/ThirdPartyAddOns
> Very early prototype with python:
> https://github.com/rmetzger/scratch/tree/learn-protobuf (basically testing
> protobuf)
> For Ruby: https://github.com/infochimps-labs/wukong
> Two new students working at Stratosphere (@skunert and @filiphaase) are
> working on this.
> The reference binding language will be for Python, but other bindings are
> very welcome.
> The best name for this so far is "stratosphere-lang-bindings".
> I created this issue to track the progress (and give everybody a chance to
> comment on this)
