Description
When attempting to create a connection to a specific table using the federated storage engine, an error is thrown.
Engine FEDERATED failed to discover table `mysql56test-cdb001`.`t_topics_indexes` with 'CREATE TABLE `t_topics_indexes` (

`topic_indexID` bigint(20) NOT NULL AUTO_INCREMENT,

`topicID` bigint(20) NOT NULL,

`index_typeID` tinyint(4) NOT NULL,
|
`index_value` varchar(1024) NOT NULL,
|
PRIMARY KEY (`topic_indexID`),
|
KEY `FK_TI_TOPICID_idx` (`topicID`),

|
KEY `UIDX_TOPICTYPEVALUE` (`topicID`,`index_typeID`,`index_value`(255)),

CONSTRAINT `FK_TI_TOPICID` FOREIGN KEY (

If I remove this key
KEY `UIDX_TOPICTYPEVALUE` (`topicID`,`index_typeID`,`index_value`(255))

it works as expected.
Here is the full create statement for the table.
CREATE TABLE `t_topics_indexes` ( `topic_indexID` bigint(20) NOT NULL AUTO_INCREMENT, `topicID` bigint(20) NOT NULL, `index_typeID` tinyint(4) NOT NULL, `index_value` varchar(1024) NOT NULL, PRIMARY KEY (`topic_indexID`), KEY `FK_TI_TOPICID_idx` (`topicID`), KEY `IDX_TYPE` (`index_typeID`), KEY `UIDX_TOPICTYPEVALUE` (`topicID`,`index_typeID`,`index_value`(255)), CONSTRAINT `FK_TI_TOPICID` FOREIGN KEY (`topicID`) REFERENCES `t_topics` (`topicID`) ON DELETE CASCADE ON UPDATE NO ACTION ) ENGINE=InnoDB AUTO_INCREMENT=14606 DEFAULT CHARSET=utf8;

All other tables on this database are able to be added normally.
