> When running {{mvn clean verify}} locally, the {{PythonPlanBinderTest}} takes 
> sometimes extremely long to finish. The latest build took more than 900 
> seconds to complete.

> Running org.apache.flink.python.api.PythonPlanBinderTest
> log4j:WARN No appenders could be found for logger 
> (org.apache.flink.python.api.PythonPlanBinderTest).

> in org.apache.flink.python.api.PythonPlanBinderTest

> Additionally I see a lot of python processes (~ 70-80) on my system doing 
> effectively nothing. This behaviour seems really strange to me. I think it 
> would be great to revisit this test case to see whether we can streamline it 
> a little bit better.
