I believe the syntax is not correct. Can you please run below command and try: +++++ CREATE TABLE IF NOT EXISTS test_ext ( NAME string, city string ) partitioned by(ID int) clustered by (NAME) into 3 buckets ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' STORED AS ORC TBLPROPERTIES ("transactional"="true"); +++++ Is it HDP or CDH or CDP ? What is the version ?
