Description:
As per http://dev.mysql.com/doc/refman/5.6/en/innodb-memcached-replication.html, to use the InnoDB memcached plugin with the MySQL binary log, enable the innodb_api_enable_binlog configuration option on the master server. This option can only be set at server boot time and hence tried to set below parameters but noticed that it is not accepting the parameter when passed through command line option to mysqld.
mysqld ... --log-bin -–innodb_api_enable_binlog=1
mysql-advanced-5.6.21]$ bin/mysqld --no-defaults --basedir=/data/ushastry/server/mysql-advanced-5.6.21 --datadir=/tmp/master --log-bin -–innodb_api_enable_binlog=1 &
[1] 30452

2014-08-01 08:35:15 30452 [Warning] No argument was provided to --log-bin, and --log-bin-index was not used; so replication may break when this MySQL server acts as a master and has his hostname changed!! Please use '--log-bin=cluster-repo-bin' to avoid this problem.

But, when used this option in configuration file then it works:
## Added options to conf file
mysql-advanced-5.6.21]$ more my.cnf |grep -A1 -B2 innodb_api_enable_binlog
[mysqld]
log_bin
innodb_api_enable_binlog=1
## Bring up mysqld
mysql-advanced-5.6.21]$ bin/mysqld --defaults-file=./my.cnf &
..
Version: '5.6.21-enterprise-commercial-advanced-log' socket: '/tmp/mysql.sock' port: 3306 MySQL Enterprise Server - Advanced Edition (Commercial)
## Confirmed that option is enabled
mysql-advanced-5.6.21]$ bin/mysql -u root -p test
..

Should work as documented
