> Doing a CTAS with limit 0 creates a 0 length parquet file which errors out during querying.  This should at least write the schema information and metadata which will allow queries to run. 
> {code}
> 0: jdbc:drill:zk=local> create table tt_nation2 as select n_nationkey, n_name, n_regionkey from cp.`tpch/nation.parquet` limit 0;
