Running via flask run hangs forever #15

As a workaround, one could run python3 server.py. I suppose it's a side effect of https://github.com/jaegertracing/jaeger-client-python/issues/50.

@carlosalberto - any ideas why this may be a thing?

@ror6ax I don't have much experience with Jaeger myself, but will take a look later today ;)

I had the same issue. Pywren's map function appears to use Threadpool. It doesn't appear that Flask is designed for this. One workaround is to put your pywren code into a script and run with subprocess. E.g.: pw_output = subprocess.check_output(["python", "run_pw.py", args])

Celery seems like it may work but I haven't got around to trying it.
