             Summary: [Python] pyarrow has a hard dependency on pandas
                 Key: ARROW-4308
                 URL: https://issues.apache.org/jira/browse/ARROW-4308
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
            Reporter: Wes McKinney
             Fix For: 0.13.0
