BUG产生具体原因不详，官方bugs.mysql.com上有提供修复这5张表的SQL文件，下载链接：http://bugs.mysql.com/file.php?id=19725

下面我们就按照文件的说明操作
  1. drop these tables from mysql:
     innodb_index_stats
     innodb_table_stats
     slave_master_info
     slave_relay_log_info
     slave_worker_info

  2. delete all .frm & .ibd of the tables above.

  3. run this file to recreate the tables above (source five-tables.sql).

  4. restart mysqld.

二、具体操作步骤
2.1、删除这5张表
drop table if exists innodb_index_stats;
drop table if exists innodb_table_stats;
drop table if exists slave_master_info;
drop table if exists slave_relay_log_info;
drop table if exists slave_worker_info;
