Description

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 (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.
