 Description   

optimizer_use_mrr is not settable via the mysqld command line. Instead, an --init script is required; This goes against the way other optimizer options operate;

MTR_VERISON=1 perl mysql-test-run.pl -start-and-exit 1st --mysqld=-optimizer_use_mrr

reports in the log:

/home/philips/bzr/maria-5.3/sql/mysqld: unknown option '--optimizer_use_mrr'

Re: optimizer_use_mrr option not settable via the mysqld command line
@@optimizer_use_mrr is now gone - it has been replaced by two flags in @@optimizer_switch. @@optimizer_switch is settable via mysqld command line, so this bug can be considered closed.
