I'm new to apache spark. Is there any difference between sbin/start-master.sh and sbin/start-all.sh ?

sbin/start-master.sh : Starts a master instance on the machine the script is executed on

sbin/start-slaves.sh : Starts a slave instance on each machine specified in the conf/slaves file

sbin/start-slave.sh : Starts a slave instance on the machine the script is executed on

sbin/start-all.sh : Starts both a master and a number of slaves 

Hope this helps
