> This seems to be the cause of the test failures in https://github.com/apache/arrow/pull/2322
> Modifying {{getSingleRecordBatchTable}} to [generate its vectors programmatically|https://github.com/apache/arrow/pull/2322/files#diff-eb6e5955a00e92f7bebb15a03f8437d1R359] (rather than deserializing hard-coded JSON), causes the new round-trip tests added in https://github.com/apache/arrow/pull/2638 to fail. The root cause seems to be that an ID is never allocated for the generated dictionary.
