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>}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
