Table created with
{noformat}
CREATE TABLE test_table (userid bigint)
clustered by (userid)
into 3 buckets
stored as orc
TBLPROPERTIES ('transactional'='true');
INSERT INTO TABLE test_table SELECT * FROM source_table;
{noformat}
Is this expected behavior ?
Change of behavior from earlier Hive versions seems to come from commit
[https://github.com/apache/hive/commit/34b0e07a3bd5002b197b749e3e5a7992e196c237#diff-ede47c0c518f8577dd3895984f019330L1037]
