1) start cluster + mysqld
2) stop cluster + mysqld
3) start cluster --initial
4) start (before starting mysqld) in background
while true; do mysql -uroot mysql "select * from ndb_apply_status"; done
5) start mysqld

ndb_apply_status will not be created in cluster *ever*

---

Maybe testcase can be reduced

(this operation is done as part of master/slave switchover by customer)
work-around: is to wait some until start using ndb_apply_status
             or add flush tables to while-loop

The function 'ndbcluster_create_ndb_apply_status_table' will delete the .frm file just before it runs the "CREATE TABLE IF NO EXISTS mysql.ndb_apply_status..." query. This triggers the code in sql_table.cc where table is in cache but does not exist on disk.

  - When an old .frm file exists on disk and is removed, we must also
    remove the table from table defintion cache with a FLUSH TABLE

Documented bugfix as follows in the 5.1.24-ndb-6.2.16 and 5.1.24-ndb-6.3.14 changelogs:

        Performing SELECT ... FROM mysql.ndb_apply_status before the mysqld
        process had connected to the cluster failed, and caused this table 
        never to be created.
