InnoDB: Error: Table “mysql”.“innodb_table_stats” not found

I've got the same error, although I'm running galera cluster with 3 nodes.
I tried following the instructions from InnoDB: Error: Table "mysql"."innodb_table_stats" not found after upgrade to mysql 5.6 but when I get to the step of running the create statements, I get the following error:

Error Code: 1813. Tablespace for table '`mysql`.`innodb_index_stats`' exists.
Please DISCARD the tablespace before IMPORT.

This made no sense to me, and when I tried to use

drop tablespace `innodb_index_stats`;

I got an SQL sysntax error.

The problem is actually very simple. Here is what happened

When you installed MySQL, the 5 InnoDB systems tables exist in two places

• inside /var/lib/mysql/mysql as 5 .frm and 5 .ibd files

• inside the data dictionary within ibdata1 (InnoDB System Tablespace)

At some point in your installation, you must have deleted ibdata1. This left the 10 InnoDB system table files inside /var/lib/mysql/mysql with no data dictionary entry.

SOLUTION

cd /var/lib/mysql/mysql
rm -f innodb_index_stats.frm
rm -f innodb_index_stats.ibd
rm -f innodb_table_stats.frm
rm -f innodb_table_stats.ibd
rm -f slave_master_info.frm
rm -f slave_master_info.ibd
rm -f slave_relay_log_info.frm
rm -f slave_relay_log_info.ibd
rm -f slave_worker_info.frm
rm -f slave_worker_info.ibd

Then, login to MySQL and run the steps from my post : InnoDB: Error: Table "mysql"."innodb_table_stats" not found after upgrade to mysql 5.6

GIVE IT A TRY !!!
