---------------------------------------
pitrou opened a new pull request #1916: ARROW-2390: [C++/Python] Map Python
exceptions to Arrow status codes
URL: https://github.com/apache/arrow/pull/1916
Instead of always returning an "unknown error" status code when a Python
exception is raised, we can easily discriminate and return e.g. a TypeError
status code when a Python TypeError is raised, etc.
