> Query: create table integer_table2 (keycolumn string, column1 int) row format delimited fields terminated by ','

> A parquet table was then created in impala and data loaded in from the first table:
> {code}
> [localhost.localdomain:21000] > create table integer_table (keycolumn string, column1 int) row format delimited fields terminated by ',' stored as parquet;
> Query: create table integer_table (keycolumn string, column1 int) row format delimited fields terminated by ',' stored as parquet

> Query: insert overwrite table integer_table select * from integer_table2
> Inserted 18 rows in 0.20s
> {code}
> The parquet file (in the format <long alphanumeric string>_data.0 and renamed) was extracted from hdfs and moved to drill's dfs. The query through sqlline hangs:
> {code}
> 0: jdbc:drill:schema=hivestg> select * from `dfs`.`/opt/drill/integer.parquet`;
> <hang>
> {code}
