Following up from https://github.com/apache/arrow/issues/1884 wherein I found that calling deserialize_pandas in the linked app.py script in the repo linked below causes the app.py process to segfault.
I initially observed this on OS X, but have since confirmed that the behavior exists on Linux as well.

And more generally: what is the right way to get a Java-based HTTP microservice to talk to a Python-based HTTP microservice using Arrow as the serialization format? I'm exchanging DataFrame type objects (they are pandas.DataFrame's on the Python side) between the two services for real-time scoring in a few xgboost models implemented in Python.
