VirtualClusterDriver and friends

[Chris Hillery <ch...@hillery.land>]

Does anyone know if there are users of the hyracks class
VirtualClusterDriver? It is launched by the script hyracks-virtual-cluster
which we ship, but I couldn't find any references on Google to that script.
It basically launches a quickie two-node Hyracks cluster as local processes.

It also uses the classes HyracksCCProcess and HyracksNCProcess, which are
utility classes for managing separate Java processes. I couldn't find any
other users of these classes either.

I'd like to revamp HyracksCCProcess and HyracksNCProcess to use the new
deployment stuff, and retire VirtualClusterDriver and he
hyracks-virtual-cluster script. This also allows eliminating those weird
toCmdLine() methods in CCConfig and NCConfig.

Thoughts?

It actually looks like hyracks-virtualcluster-maven-plugin has very rough
duplicates of those classes; it doesn't use them directly. So I don't think
my change breaks that (I'm still able to build locally with all those
changes/deletions at least). But I will look more closely at that plugin to
see if there should be similar changes made there, or if perhaps it COULD
make use of HyracksCCProcess and friends to remove some code duplication.

Thanks,

I believe that is part of the Hyracks virtual cluster maven plugin, which
we use for a few Hyracks integration tests. The maven plugin starts the
hyracks cluster before the module starts all of its tests and tears it down
afterward.
