Apache Spark startup - address of master

[Frank Leonhardt]

The rc.d/spark_worker service script points the program to a master 
using the current hostname, which rather defeats the whole point of a 
cluster.

I don't really want to edit the startup script if I can avoid it. Is 
there a clean way of making look at the actual master? There's not a lot 
of FreeBSD-specific documentation around, but if there is any a pointer 
to that would be great.

Thanks, Frank.
