Description

I've seen that the HBOSS unit tests will fail for me with a ConnectionLoss exception. This is resolved when I force ipv4. My hunch is that we don't block for curator to become connected, and because of my local setup, the ipv6 lookup happens first and has to time-out. The test starts running but Curator hasn't yet become connected, so we fail with a ConnectionLoss in the test itself.

We should wait for Curator to become connected and maybe add -Djava.net.preferIPv4Stack=true to surefire opts
