> Following GitHub PR #2039 (resolution to ARROW-2578), the random generator for random object ids is now using a constant default seed, meaning all processes will generate the same sequence of random ids:
> {code:java}
> $ python -c "from pyarrow import plasma; print(plasma.ObjectID.from_random())"
> ObjectID(d022e7d520f8e938a14e188c47308cfef5fff7f7)
> $ python -c "from pyarrow import plasma; print(plasma.ObjectID.from_random())"
> ObjectID(d022e7d520f8e938a14e188c47308cfef5fff7f7)
> {code}
> As a sidenote, the plasma test suite should ideally test for this.
