Summary: incorrect HS2 null handling introduced by IMPALA-7477
Key: IMPALA-7588
URL: https://issues.apache.org/jira/browse/IMPALA-7588
Project: IMPALA
Issue Type: Bug
Components: Backend
Reporter: Tim Armstrong
Assignee: Tim Armstrong
[~boroknagyz] reported this issue with the HS2 endpoint:
Reproduction:
{noformat}
create table null_table (int_field int, float_field float, double_field double,
string_field string);
insert into table null_table values (1, 3.14, 3.14, 'abc'), (2, 4.12, 4.12,
'def'), (NULL, NULL, NULL, NULL);
{noformat}
>From JDBC client (only tried Hive JDBC client)
{noformat}
select * from null_table;
0 | 0.0 | 0.0 | null
2 | 4.12 | 4.12 | 'def'
0 | 0.0 | 0.0 |
{noformat}
The bug is with handling of nulls in the conversion functions, specifically
output_row_idx isn't incremented.
