> Key: HIVE-24238
> URL: https://issues.apache.org/jira/browse/HIVE-24238
> Project: Hive
> Issue Type: Bug
> Components: Avro
> Affects Versions: 3.1.0, 3.1.2
> Reporter: Gabriel C Balan
> Priority: Minor
>
> {noformat:title=Reproducer}
> create table avro_reproducer (key int, union_col uniontype <int, string>) stored as avro location '/tmp/avro_reproducer';
> INSERT INTO TABLE avro_reproducer values (0, create_union(0, 123, 'not me')), (1, create_union(1, -1, 'me, me, me!'));
> --these queries are ok:
> select count(*) from avro_reproducer;
> select * from avro_reproducer;
> --these queries are not ok
> select * from avro_reproducer order by union_col;
> select * from avro_reproducer sort by key;
> select * from avro_reproducer order by 'does not have to be a column, really';
> {noformat}
> I have verified this reproducer on CDH703, HDP301.
> It seems the issue is restricted to AVRO; this reproducer does not trigger failures against textfile tables, orc tables, and parquet tables.
> Also, the issue is restricted to vectorized execution; it goes away if I set hive.vectorized.execution.enabled=false
