Comment 1 for bug 1536663

Verified. Looks like the tokudb_rpl_lookup_rows disabled alone leads to inconsistency in a table without PK on a slave.

master [localhost] {msandbox} (world) > show create table City\G
*************************** 1. row ***************************
       Table: City
Create Table: CREATE TABLE `City` (
  `Name` char(35) NOT NULL DEFAULT '',

  `District` char(20) NOT NULL DEFAULT '',
  `Population` int(11) NOT NULL DEFAULT '0',
  KEY `CountryCode` (`CountryCode`)
) ENGINE=TokuDB DEFAULT CHARSET=latin1
1 row in set (0.00 sec)
