> 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
> Assignee: Philipp Moritz
> Priority: Minor
> Fix For: 0.3.0
>
>
> 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.
