[Bug 1468185] [NEW] Function 'innodb' already exists and other errors

[Mitar]

Public bug reported:

When running MySQL 5.6 I am getting the following errors in the log:

2015-06-24 05:24:20 893 [ERROR] Function 'innodb' already exists
2015-06-24 05:24:20 893 [Warning] Couldn't load plugin named 'innodb' with soname 'ha_innodb.so'.
2015-06-24 05:24:20 893 [ERROR] Function 'federated' already exists

2015-06-24 05:24:20 893 [ERROR] Function 'archive' already exists
2015-06-24 05:24:20 893 [Warning] Couldn't load plugin named 'archive' with soname 'ha_archive.so'.

The reason seems to be that postinit script adds those entries to the
plugin table:

mysql> SELECT * FROM mysql.plugin;
+-----------+-----------------+
| name      | dl              |
+-----------+-----------------+
| innodb    | ha_innodb.so    |
| federated | ha_federated.so |
| blackhole | ha_blackhole.so |
| archive   | ha_archive.so   |
+-----------+-----------------+

But those files do not exist for MySQL 5.6. Search shows that they exist
only for MairaDB.

mysql-server-5.6: 5.6.19-0ubuntu0.14.04.1
Ubuntu 14.04.2 LTS

I would expect that there would be no errors when starting a clean
installation of MySQL.

This was also reported here by another user:

Removing those rows from the plugin table makes the errors go away.
