Hi All
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.
Is it bug ? or ......
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
