I'm trying to do CRUD operations in Hive and able to successfully run insert query however when I tried to run update and delete getting the below exception.
FAILED: SemanticException [Error 10294]: Attempt to do update or delete using transaction manager that does not support these operations.
List of the queries I ran
CREATE TABLE students (name VARCHAR(64), age INT, gpa DECIMAL(3, 2))
CLUSTERED BY (age) INTO 2 BUCKETS STORED AS ORC;
INSERT INTO TABLE students
VALUES ('fred flintstone', 35, 1.28), ('barney rubble', 32, 2.32);
CREATE TABLE pageviews (userid VARCHAR(64), link STRING, came_from STRING)
PARTITIONED BY (datestamp STRING) CLUSTERED BY (userid) INTO 256 BUCKETS STORED AS ORC;
INSERT INTO TABLE pageviews PARTITION (datestamp = '2014-09-23')
VALUES ('jsmith', 'mail.com', 'sports.com'), ('jdoe', 'mail.com', null);
INSERT INTO TABLE pageviews PARTITION (datestamp)
VALUES ('tjohnson', 'sports.com', 'finance.com', '2014-09-23'), ('tlee', 'finance.com', null, '2014-09-21');

Update and delete queries I'm trying to run
update students1 set age = 36 where name ='barney rubble';
update students1 set name = 'barney rubble1' where age =36;
delete from students1 where age=32;
Hive Version : 2.1(Latest)
Note : I'm aware that Hive is not for Update and Delete commands(on BigData set) still trying to do, to get awareness on Hive CRUD operations.
Can someone point/guide me the where I'm going wrong on update/delete queries.
