Github user zentol commented on the issue:
https://github.com/apache/flink/pull/3838
When running the example against a local cluster i got this exception
```
java.io.IOException: java.io.IOException: The given HDFS file URI
(hdfs:/tmp/flink_cache_-4117839671387669278) did not describe the HDFS
NameNode. The attempt to use a default HDFS configuration, as specified in the
'fs.hdfs.hdfsdefault' or 'fs.hdfs.hdfssite' config parameter failed due to the
following problem: Either no default file system was registered, or the
provided configuration contains no valid authority component (fs.default.name
or fs.defaultFS) describing the (hdfs namenode) host and port.

> Python API for streaming applications

> Key: FLINK-5886
> URL: https://issues.apache.org/jira/browse/FLINK-5886
> Project: Flink
> Issue Type: New Feature
> Components: Python API
> Reporter: Zohar Mizrahi
> Assignee: Zohar Mizrahi
>
> A work in progress to provide python interface for Flink streaming APIs. The
> core technology is based on jython and thus imposes two limitations: a. user
> defined functions cannot use python extensions. b. the python version is 2.x
> The branch is based on Flink release 1.2.0, as can be found here:
> https://github.com/zohar-pm/flink/tree/python-streaming
> In order to test it, someone can use IntelliJ IDE. Assuming IntelliJ was
> setup properly (see:
> https://ci.apache.org/projects/flink/flink-docs-release-1.3/internals/ide_setup.html),
> one can run/debug {{org.apache.flink.python.api.PythonStreamBinderTest}},
> which in return will execute all the tests under
> {{/Users/zohar/dev/pm-flink/flink-libraries/flink-python/src/test/python/org/apache/flink/python/api/streaming}}
