Anthony Hsu created HIVE-15190:
----------------------------------
Summary: Field names are not preserved in ORC files written with
ACID
Key: HIVE-15190
URL: https://issues.apache.org/jira/browse/HIVE-15190
Project: Hive
Issue Type: Bug
Affects Versions: 2.1.0
Reporter: Anthony Hsu
Assignee: Anthony Hsu
To repro:
{noformat}
drop table if exists orc_nonacid;
drop table if exists orc_acid;
create table orc_nonacid (a int) clustered by (a) into 2 buckets stored as orc;
create table orc_acid (a int) clustered by (a) into 2 buckets stored as orc
TBLPROPERTIES('transactional'='true');
insert into table orc_nonacid values(1), (2);
insert into table orc_acid values(1), (2);
{noformat}
Running {{hive --service orcfiledump <file>}} on the files created by the
{{insert}} statements above, you'll see that for {{orc_nonacid}}, the files
have schema {{struct<a:int>}} whereas for {{orc_acid}}, the files have schema
{{struct<operation:int,originalTransaction:bigint,bucket:int,rowId:bigint,currentTransaction:bigint,row:struct<_col0:int>>}}.
The last field {{row}} should have schema {{struct<a:int>}}.
