When I create partitioning table accross disks,show this error.I have seen refman-5.7-en.html-chapter/partitioning.html#partitioning-overview,but I don't know why? have any idea can resolve this problem? thanks.

sql:

CREATE TABLE tsss (id INT, purchased DATE) PARTITION BY RANGE( YEAR(purchased) ) SUBPARTITION BY HASH( TO_DAYS(purchased) ) ( PARTITION p0 VALUES LESS THAN (1990) ( SUBPARTITION s0 DATA DIRECTORY = '/Users/tianjingcheng/par/tj0/data' INDEX DIRECTORY = '/Users/tianjingcheng/par/tj0/idx', SUBPARTITION s1 DATA DIRECTORY = '/Users/tianjingcheng/par/tj1/data' INDEX DIRECTORY = '/Users/tianjingcheng/par/tj1/idx' ), PARTITION p1 VALUES LESS THAN (2000) ( SUBPARTITION S2 DATA DIRECTORY = '/Users/tianjingcheng/par/tj2/data' INDEX DIRECTORY = '/Users/tianjingcheng/par/tj2/idx', SUBPARTITION S3 DATA DIRECTORY = '/Users/tianjingcheng/par/tj3/data' INDEX DIRECTORY = '/Users/tianjingcheng/par/tj3/idx' ) );

error:ERROR 1031 (HY000): Table storage engine for 'tsss' doesn't have this option
