Vsevolod Ostapenko created KYLIN-3121:
-----------------------------------------
Summary: NPE while executing a query with two left outer joins and
floating point expressions on nullable fields
Key: KYLIN-3121
URL: https://issues.apache.org/jira/browse/KYLIN-3121
Project: Kylin
Issue Type: Bug
Components: Query Engine
Affects Versions: v2.2.0
Environment: HDP 2.5.6, Kylin 2.2.0
Reporter: Vsevolod Ostapenko
Assignee: liyang
Queries that include two (or more) left outer joins and contain floating point
expressions that operate on the fields that contain integer NULL values (due to
left outer join) fail in-flight with NullPointerExceptions.
As an example, the following query generates NPE on either of the two
expressions:
* 100.0 * t2.media_gap_call_count
* 1.0 * NULLIF(t1.active_call_count, 0)
{{with
t1
as
(
select
d1.cell_name,
count(distinct a1.call_id) as active_call_count
from
zetticsdw.a_vl_hourly_v a1
inner join
zetticsdw.d_cell_v d1
on
a1.cell_key = d1.cell_key
where
d1.region_3 = 'Mumbai'
and
a1.thedate = '20171011'
and
a1.thehour = '00'
and
a1.active_call_flg = 1
group by
d1.cell_name
),
t2
as
(
select
d1.cell_name,
count(distinct a1.call_id) as media_gap_call_count
from
zetticsdw.a_vl_hourly_v a1
inner join
zetticsdw.d_cell_v d1
on
a1.cell_key = d1.cell_key
where
d1.region_3 = 'Mumbai'
and
a1.thedate='20171011'
and
a1.thehour = '00'
and
a1.media_gap_call_flg = 1
group by
d1.cell_name
)
,
t3
as
(
select
d1.cell_name,
sum(a1.ow_call_flg) one_way_call_count,
sum(a1.succ_call_flg) successfull_call_count
