CREATE VIEW dfs.tmp.`fact_a` AS select distinct CAST(columns[0] as INTEGER) as
b_id, CAST(columns[1] as INTEGER) as c_id, CAST(columns[2] as DATE) as a_date,
CAST(columns[3] AS INTEGER) as a_value from
dfs.root.`/Users/rsingh/Downloads/apache-drill-1.0.0/sample-data/master-data.csv`
order by b_id, c_id, a_date;
CREATE VIEW dfs.tmp.`dim_c` AS select CAST(columns[1] as INTEGER) as c_id,
CAST(columns[12] as VARCHAR) as c_desc, CAST(columns[11] as INTEGER) as c4_id,
CAST(columns[10] as VARCHAR) as c4_desc, CAST(columns[9] as INTEGER) as c3_id,

while trying to join the views getting CanNotPlanException(huge trace can not
paste here)
join query
select a11.c_id c_id,
max(a12.c_desc) c_desc,
max(a12.c4_desc) c4_desc,
sum(a11.a_value) a_value
from dfs.tmp.`fact_a` a11
join dfs.tmp.`dim_c` a12
on (a11.c_id =a12.c_id)
group by a11.c_id;
