Description

Hi,
I have one table with VARCHAR and CHAR datatypes.My target table has structure like this :--

CREATE EXTERNAL TABLE test_table(
dob string COMMENT '',
version_nbr int COMMENT '',
record_status string COMMENT '',
creation_timestamp timestamp COMMENT '')
PARTITIONED BY (
src_sys_cd varchar(10) COMMENT '',batch_id string COMMENT '')
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '|'
STORED AS ORC
LOCATION
'/test/test_table';
My source table has structure like below :--
CREATE EXTERNAL TABLE test_staging_table(
dob string COMMENT '',
version_nbr int COMMENT '',
record_status string COMMENT '',
creation_timestamp timestamp COMMENT ''
src_sys_cd varchar(10) COMMENT '',
batch_id string COMMENT '')
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '|'
STORED AS ORC
LOCATION
'/test/test_staging_table';

We were loading data using pig script. Its a direct load, no transformation needed. But when i was checking test_table's data in hive. It is giving belowmentioned error:
