[jira] [Created] (ARROW-788) Possible nondeterminism in Tensor serialization code

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.
