[jira] [Created] (HIVE-20990) ORC, group by, case: java.lang.AssertionError: Output column number expected to be 0 when isRepeating

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:
