Wes McKinney commented on PARQUET-1420:
---------------------------------------

We probably want to remove dependency on these symbols from the unit tests

> Thirft-generated symbols don't have any {{PARQUET_EXPORT}}-like annotation, so they are not reachable from the Parquet DLL. In turn this makes it impossible to link Parquet unit tests with the Parquet DLL (instead of the Parquet static lib). I'm not sure it can impact other applications.
