Why do you say to do that first?

At least there are times when Minerva is using both its executors.
However, it looks like we could get by with half the current number of
the Hadoop labeled machines without impacting anything.

Maybe we can just define a useful set of labels to sets of nodes and
encourage people to tie builds to them rather than specific machines.
