The following test fails with error "ERROR HY000: Tables have different definitions":

--source include/have_partition.inc

--source include/have_archive.inc

CREATE TABLE t1(a INT NOT NULL AUTO_INCREMENT PRIMARY KEY) ENGINE=ARCHIVE PARTITION BY HASH (a) PARTITIONS 4;

CREATE TABLE t2 LIKE t1;

ALTER TABLE t2 REMOVE PARTITIONING;

ALTER TABLE t1 EXCHANGE PARTITION p1 WITH TABLE t2;

DROP TABLE t1,t2;

While performing exchange partition we call mysql_compare_tables()/ha_archive::check_if_incompatible_data(). In MariaDB this function always return COMPATIBLE_DATA_NO.

Covered by the following tests: parts.partition_mgm_lc1_archive parts.partition_exchange_archive parts.partition_mgm_lc0_archive rpl.rpl_partition_archive. Enable them when this bug is fixed.
