how launch mapred in hadoop 2.0.4?

In hadoop mapreduce there is the need to launch mapred (mapred start), or
launching yarn ( $sbin/yarn-daemon.sh start resourcemanager ;
sbin/yarn-daemon.sh start nodemanager) is the same thing?

Best regards,

The mapred command is needed to launch the JobHistoryServer.
