Why alluxio start workers need passwd ,I have set login by ssh no [sudo] password for ????

@mseaspring running bin/alluxio-start.sh all will attempt to ssh to all worker machines to start the worker process ... to avoid having to input password, you can add the public ssh key of the machine on which you are running bin/alluxio-start.sh all to ~/.ssh/authorized_keys on all worker machines
