The project pipeline that I am working on involves grabbing Twitter data from a ZMQ publisher .py script, then ZMQ subscriber.py | logstash - f simple-config.rb (json), then running elasticsearch. An issue I am running into is the second part of the pipeline, pipping the subscriber script and logstash. Everytime I execute the pipe command in Ubuntu 16.04 LTS, the cursor turns into a cross. When I click anywhere, it takes a screenshot and terminates logstash. See attached pic for the output.  
The syntax error shows up after I click, then logstash stops. I am able to run the ZMQS.py script standalone with no issues so I don't know why it is saying there is a syntax error. I have tried this on 5.6.1 and 5.6.4, both have same results. Any idea?
