Steps to reproduce :-
1)Create a table -> table_1
CREATE TABLE `table_1` (
`id` int(11) NOT NULL,
`time_slice_size` int(11) DEFAULT NULL
) ENGINE=Columnstore DEFAULT CHARSET=latin1;
2)Insert data in table_1 :-
insert into table_1 values(1,60);
insert into table_1 values(2,60);
3)Create another table -> table_2
CREATE TABLE `table_2` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`start_timestamp` timestamp NULL DEFAULT NULL,
`end_timestamp` timestamp NULL DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=9155 DEFAULT CHARSET=latin1;
4)Insert data into table_2 :-
insert into table_2 values (1,'2016-10-10 08:00:00','2016-10-10 09:00:00');
insert into table_2 values (2,'2016-10-10 08:00:00','2016-10-10 09:00:00');

5)Run the below query :-
select tb1.time_slice_size,tb2.id tb2_id, tb2.end_timestamp, tb2.start_timestamp FROM table_1 tb1, table_2 tb2 where tb1.id = tb2.id and tb2.id = 1;
This returns two row it should return one row.

Same problem is with below query(with IN )

select tb1.time_slice_size,tb2.id tb2_id, tb2.end_timestamp, tb2.start_timestamp FROM table_1 tb1, table_2 tb2 where tb1.id = tb2.id and tb2.id in (1);

but the weird thing is that when i add one more id then it returns correct result,see below :-
select tb1.time_slice_size,tb2.id tb2_id, tb2.end_timestamp, tb2.start_timestamp FROM table_1 tb1, table_2 tb2 where tb1.id = tb2.id and tb2.id in (1,3);
