Gabriel C Balan created HIVE-24238:
--------------------------------------
Summary: ClassCastException in order-by query over avro table with
uniontype column
Key: HIVE-24238
URL: https://issues.apache.org/jira/browse/HIVE-24238
Project: Hive
Issue Type: Bug
Components: Avro
Affects Versions: 3.1.2, 3.1.0
Reporter: Gabriel C Balan
{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';

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.
