    The format for specifying columns is described here: https://github.com/apache/parquet-mr/blob/master/parquet_cascading.md#21-projection-pushdown-with-thriftscrooge-records

    The format for specifying columns is described here: https://github.com/apache/parquet-mr/blob/master/parquet_cascading.md#21-projection-pushdown-with-thriftscrooge-records

    Note that the format described there says that multiple globs can be combined with a ; character. Instead, we use a Set() here and will eventually join the set on the ; character for you.
