This error appears to be related to the patch of HIVE-10591.
Steps to reproduce (Hive QL):
{noformat}
DROP TABLE IF EXISTS orc_drop_column;
CREATE TABLE orc_drop_column (`id` int, `name` string, `description` string,
`somevalue` double, `someflag` boolean, `somedate` timestamp) STORED AS ORC;
INSERT INTO TABLE orc_drop_column select * from (select 1, 'my_name',
'my_desc', 5.5, true, '2016-08-25 06:00:00') a;
ALTER TABLE orc_drop_column SET SERDE
'org.apache.hadoop.hive.serde2.columnar.ColumnarSerDe';
ALTER TABLE orc_drop_column REPLACE COLUMNS (
`id` int,
`name` string
);
ALTER TABLE orc_drop_column SET SERDE
'org.apache.hadoop.hive.ql.io.orc.OrcSerde';
SELECT id, name FROM orc_drop_column;
