Guillaume created HIVE-20990:
--------------------------------
Summary: ORC, group by, case: java.lang.AssertionError: Output
column number expected to be 0 when isRepeating
Key: HIVE-20990
URL: https://issues.apache.org/jira/browse/HIVE-20990
Project: Hive
Issue Type: Bug
Components: Vectorization
Affects Versions: 3.0.0
Environment: * Hive 3.0.0 from hdp 3.0.1.
* centos 7
* 5 datanodes, 2 masters
Reporter: Guillaume
Run this to replicate:
{code:sql}
drop table if exists ds;
create table ds stored as orc as select
inline(array(
struct('gmail.com'), -- when branch of the case statement
struct('apache.org') -- else branch of the case statement
)) as (domain)
;
select
case
when domain='gmail.com' then 'gmail'
else coalesce(domain, 'other')
end as domaingroup
from ds
group by 1 -- useless (datawise) for this example, but triggers the bug.
;
{code}
Exceptions out with:
{noformat}
java.lang.RuntimeException: java.lang.AssertionError: Output column number
expected to be 0 when isRepeating
{noformat}
Full exception is shown below.
Of interest:
* if the case is removed (eg. replaced only by the else clause), the query
works,
* if only the else clause from the case matches, the query works,
* replacing the case by a bunch of nested if does not change anything,
* removing the group by and the query works,
* replacing the table (ds) by a CTE and the query works.
Workaround, at the cost of performance:
{code:java}
set hive.vectorized.execution.enabled = false;
{code}
Full exception:
{noformat}
