-------------------------------------
Summary: Iceberg: Concurrent Insert and IOW produce incorrect
result
Key: HIVE-28366
URL: https://issues.apache.org/jira/browse/HIVE-28366
Project: Hive
Issue Type: Bug
Components: Iceberg integration
Affects Versions: 4.0.0
Reporter: Denys Kuzmenko
1. create a table and insert some data:
{code}
create table ice_t (i int, p int) partitioned by spec (truncate(10, i)) stored
by iceberg;
insert into ice_t values (1, 1), (2, 2);
insert into ice_t values (10, 10), (20, 20);
insert into ice_t values (40, 40), (30, 30);
{code}
Then concurrently execute the following jobs:
Job 1:
{code}
insert into ice_void select i*100, p*100 from ice_void;
{code}
Job 2:
{code}
insert overwrite ice_void select i+1, p+1 from ice_void;
{code}
If Job 1 finishes first, Job 2 still succeeds for me, and after that the table
content will be the following:
{code}
2 2
3 3
11 11
21 21
31 31
41 41
100 100
200 200
1000 1000
2000 2000
3000 3000
4000 4000
{code}
