-----------------------------------
Summary: Using UNION ALL operator on tables of different storage
format
Key: HIVE-11063
URL: https://issues.apache.org/jira/browse/HIVE-11063
Project: Hive
Issue Type: Bug
Components: File Formats
Affects Versions: 1.0.0
Environment: Centos 6.6
Reporter: sanjiv singh
I was trying to combine records of two tables using UNION ALL.
One table testTableText is on TEXT format and another table testTableORC is on
ORC format. It is failing with given error.
It seems error related to input format.
See the given scenario :
Hive Version : 1.0.0
-- Create TEXT Table
create table testTableText(id int,name string)row format delimited fields
terminated by ',';
-- Create ORC Table
create table testTableORC(id int ,name string ) clustered by (id) into 2
buckets stored as orc TBLPROPERTIES('transactional'='true');
-- query with UNION
SELECT * FROM testTableORC
UNION ALL
SELECT * FROM testTableText ;
-- Error :
Query ID = cloud_20150618225656_fbad7df0-9063-478e-8b6e-f0631d9978e6
Total jobs = 1
Launching Job 1 out of 1
Number of reduce tasks is set to 0 since there's no reduce operator
