[jira] [Created] (ARROW-2588) [Plasma] Random unique ids always use the same seed


Antoine Pitrou created ARROW-2588:
-------------------------------------

             Summary: [Plasma] Random unique ids always use the same seed
                 Key: ARROW-2588
                 URL: https://issues.apache.org/jira/browse/ARROW-2588
             Project: Apache Arrow
          Issue Type: Bug
          Components: Plasma (C++)
            Reporter: Antoine Pitrou


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.
