      The following mondrian query (query12.q) failed sql parser:

      0: jdbc:drill:schema=dfs> select customer.country as c0, customer.state_province as c1, customer.city as c2, customer.customer_id as c3, fullname as c4, fullname as c5, customer.gender as c6, customer.marital_status as c7, customer.education as c8, customer.yearly_income as c9 from customer as customer, sales_fact_1997 as sales_fact_1997, time_by_day as time_by_day where sales_fact_1997.customer_id = customer.customer_id and sales_fact_1997.time_id = time_by_day.time_id and time_by_day.the_year = 1997 group by customer.country, customer.state_province, customer.city, customer.customer_id, fullname, customer.gender, customer.marital_status, customer.education, customer.yearly_income having fullname LIKE '%Jeanne%' order by customer.country ASC NULLS LAST, customer.state_province ASC NULLS LAST, customer.city ASC NULLS LAST, fullname ASC NULLS LAST;

      Error: exception while executing query (state=,code=0)

      If I qualify the column name 'fullname' as 'customer.fullname', then query works.

      The thing is with similar but a bit simplified query that I do not qualify the column name, it works fine. Only fails for this particular query. So far, I failed to isolate the problem. For example, the following query works without qualifying the column name:

      0: jdbc:drill:schema=dfs> select customer.country as c0, fullname as c4 from customer as customer group by customer.country, fullname limit 4;

      c0 c4
