Subject [jira] [Created] (ARROW-788) Possible nondeterminism in Tensor serialization code
Date Fri, 07 Apr 2017 22:32:41 GMT
Philipp Moritz created ARROW-788:
------------------------------------

             Summary: Possible nondeterminism in Tensor serialization code
                 Key: ARROW-788
                 URL: https://issues.apache.org/jira/browse/ARROW-788
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++, Python
            Reporter: Philipp Moritz
            Priority: Minor


The Ray nondeterminism tests are failing on
https://github.com/ray-project/ray/pull/436 (moving to Arrow's Tensor serialization code).

This might mean that there is some nondeterminism (like uninitialized memory) in the IPC file
written by the Arrow Tensor serializer. I'm investigating it now, please let me know if you
have an idea what the problem could be.
