[jira] [Created] (FLINK-6384) PythonStreamer does not close python processes

Till Rohrmann created FLINK-6384:
------------------------------------

             Summary: PythonStreamer does not close python processes
                 Key: FLINK-6384
                 URL: https://issues.apache.org/jira/browse/FLINK-6384
             Project: Flink
          Issue Type: Bug
          Components: Python API
    Affects Versions: 1.3.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.3.0


The {{PythonStreamer}} opens a new process calling the python binary to check whether the binary is available. This process won't get closed leading to an excessive number of open python processes when running the {{PythonPlanBinderTest}}. I'm not entirely sure whether we need this extra process, because the actual python call with the python code would also fail if there is no python binary available.
