when I create table in mysql8.0 with partition and data directory , the error happened: ERROR 1525 (HY000): Incorrect path value: '/var/lib/mysql/p1'

Pratiksha

CREATE TABLE employees1 (

    id INT NOT NULL auto_increment ,

    name varchar(128),

    primary key(id)

) ENGINE=INNODB  

    PARTITION BY LIST(id%10)(

    PARTITION p1 VALUES IN (0,1,2,3,4)

    INDEX DIRECTORY = '/var/lib/mysql/p1'

    DATA DIRECTORY = '/var/lib/mysql/p1',

    PARTITION p2 VALUES IN (5,6,7,8,9)

    INDEX DIRECTORY = '/var/lib/mysql/p2'

    DATA DIRECTORY = '/var/lib/mysql/p2'
