You can start the slave services on the slave nodes manually (they
will cluster automatically, if the configuration is valid across your
heterogeneous setup).

Use 'hadoop-daemon.sh {stop,start}
{tasktracker,datanode,secondarynamenode}' to toggle individual daemons
on target machines.

[You may write a script to achieve an automation via this, perhaps --
instead of letting the default slaves.sh being used via
hadoop-daemons.sh]
