>            Reporter: Anthony Hsu

> To repro:
> {noformat}
> SET hive.exec.schema.evolution = false;
> CREATE TABLE avro_orc_partitioned_uniontype (a uniontype<boolean, string>) PARTITIONED
BY (b int) STORED AS ORC;
> INSERT INTO avro_orc_partitioned_uniontype PARTITION (b=1) SELECT create_union(1, true,
value) FROM src LIMIT 5;
> ALTER TABLE avro_orc_partitioned_uniontype SET FILEFORMAT AVRO;
> SELECT * FROM avro_orc_partitioned_uniontype;
> {noformat}
> The exception you get is:
> {code}
> java.io.IOException:org.apache.hadoop.hive.ql.metadata.HiveException: java.lang.ClassCastException:
java.util.ArrayList cannot be cast to org.apache.hadoop.hive.serde2.objectinspector.UnionObject
> {code}
> The issue is that StandardUnionObjectInspector was creating and returning an ArrayList
rather than a UnionObject.
