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'
