    https://github.com/apache/flink/pull/3838
  
    Regarding the exception - 
    ```java.io.IOException: java.io.IOException: The given HDFS file URI ...```
    
    In general, using the python interface requires a valid configuration of 
shared file system (.e.g HDFS), which designed to distribute the python files. 
    Someone can bypass this issue by set the second argument to 'True' when 
calling to ```env.execute(...)``` in the python script.

> 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}}
