I think DrillHiveTable or other schema-aware table would return
RelRecordType (in Calcite), when calling typeFactory.createStructType() as
RowType.
For DrillDynamicTable, which is schema-less, the RowType would be
RelDataTypeDrillImpl.

>
> Running a select * from hive.table limit 0 does not return (hangs).
> Select * from hive.table limit 1 works fine
> Hive table is about 6GB with 330 files with parquet using snappy compression.
> Data types are int, bigint, string and double.
> Querying directory with parquet files through the DFS plugin works fine
> select * from dfs.root.`/user/hive/warehouse/database/table` limit 0;
